Jeffy

"Heeyyy, my name is Jeffy, see? It says it on my shirt, Je-ffy. You wanna see my pencil, you wanna see it."

- His greeting, this one specifically in Who Wants To Be A Millionaire? Episode 3 Jeffy Jeffy, or simply Jeffy is a main character in SuperMarioLogan. Portrayed by Lance, Jeffy is a mentally disabled kid (however, at some points he can be somewhat intelligent) who has a tendency to put pencils in his nose and spank his diaper often. He is also spoiled and has many characteristics of being a brat, similar to Junior. He is reluctantly looked after by Mario, whom he calls "Daddy", and his enthusiastic girlfriend Rosalina, whom he calls "Mommy". He likes to stick his 'Pee Pee' in the Cheerio box. People say when he spanks his diaper, 'he is fapping'. In 'Happy Merry Christmas!', he saw Santa Claus and locked him outside, without his bag and took a lot of the toys. WHOEVER GOT RID OF EVERYTHING PUT IT BACK NOW!

Personality
Jeffy is flat-out retarded, outranking Tony on the Wiki's list of character attribute rankings. He has a habit of spanking his diaper despite some fans which strangely happens to be outside his pants. When he is called a "bad boy," he tends to throw a tantrum by throwing his head onto any surface, but calms down when he is called a "good boy." His parents delivered him to Mario possibly because they were too annoyed by his stupidity, and did not want to deal with him any further. Not much is known about his relationship between Junior and Joseph, despite the fact that both called him awesome after surviving a game of Russian Roulette once. Rosalina is more loving and caring towards Jeffy, to the point of acting like a motherly figure, and calling Mario off whenever he abused Jeffy.

Jeffy, however, has been shown to act smart, but in a dumb way at times, such as in "Jeffy's Homework!", when he reasoned that 8-4=8, since they are taking 4 out of the equation, even going on a profanity-laced rant. Later, in "Jeffy's Bedtime!", he called the nameless tall character in Green Eggs and Ham a liar, since the character claimed that he liked the green eggs and ham, but the illustration clearly shows that he didn't eat the ham at all. According to him, he used to live at 7 Jeffy before being dropped off at Mario's door. Jeffy also tends to soil his pants a lot. While there's no doubt that he's retarded, it's implied that Jeffy is not as handicapped as he lets on, and that he may be self aware enough to be a brat. For example, in "First Day Of School! ", he was smart enough to tell the teacher off for assigning a 10 page paper that was due the next day (though he got a note sent home for doing so).

He has also shown a bratty side, even more so than Junior, as seen in "Jeffy's Bedtime!", where he demands that Mario and Rosalina make him green eggs and ham, in "Jeffy Gets Potty Trained!", when he demands that Rosalina give him marshmallows instead of peas, in "The Hitman!", where he wanted Jello after Mario gave him green beans, and he refused to eat his nuggets because he wasn't given 20 toys and threw them away, and finally in "Locked Out", where he demanded for chocolate cake, cried when Mario didn't give him chocolate cake and locked Mario out just so he could teabag Mario's plate of cake. He also flips his desk in "First Day Of School! " because the teacher assigned a 10 page essay that was due the next day and cusses (mostly the F-word) at Jackie Chu.

Jeffy sometimes seems have a prankster personality as in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Junior. During both of these videos, he seems to be less stupid, causing many fans to think that this could be a normal version of Jeffy.

Sick Jeffy
Sick Jeffy  is a form of Jeffy with the flu, taking way greater effect than normal Jeffy would with other characters such as Mario, and having a chance of giving others the flu. His appearance also changes to rundown, tired, and overall extremely droopy.

Smart Jeffy
Smart Jeffy is a form of Jeffy, appearing only in the episode of the same name, who is incredibly smart compared to his normal form, due to his pencil having impaled his brain thanks to a freak accident indirectly caused by Junior. However, at the end of the video, Jeffy sneezed, blowing his pencil out back down his nose, leaving a hole in his brain, and reverting him to his normal form.

Toothless Jeffy
Toothless Jeffy is another form of Jeffy. It appears in Jeffy Loses His Teeth!, and swears alot at Mario for not getting paid much.

Mario
Mario is Jeffy's guardian. Mario has a strong dislike for Jeffy, while with Jeffy himself, he appears to like Mario. Jeffy usually calls Mario "Daddy", even though Mario is not Jeffy's birth nor adopted father and keeps telling him he's not.

Mario is incredibly unhappy that Jeffy was dropped off at his apartment door and loathes the fact he has custody of the little brat. Mario gets frustrated with Jeffy in nearly every video they appear in together. Most of the time however, it seems that Jeffy annoys Mario not on purpose. Mario has tried multiple times to get rid of Jeffy, but to avail. Most of his attempts ended with Jeffy back at Mario's step, or in the case of Where's Jeffy?, Mario going back to get Jeffy because he had Rosalina's necklace, only to find out that Jeffy gave it to a squirrel. In Bowser Junior's Nerf War!, both Mario and Jeffy even made a small cameo appearance right at the end and Mario attacked Jeffy with a Nerf gun. Because of his overwhelming stupidity (or possible retardation), Jeffy gets Mario into trouble way too much to be considered funny.

Although Mario gets annoyed with Jeffy most of the time, he has been shown to care about Jeffy, as shown in Jeffy's Mistake! when Black Yoshi was about to kill Jeffy; in Rosalina's Parents!, Mario gets scared when he assumes Jeffy fell to his death, and freaks out when Jeffy gets abducted. It's possible Mario might only care just so Rosalina won't break up with him.

Chef Pee Pee
Jeffy seems to like Chef Pee Pee. Chef Pee Pee however does not seem to have patience for Jeffy, almost as much as Mario; for instance, he got annoyed with Jeffy when Mario and him were trying to get Jeffy to eat his green beans. Chef Pee Pee also seemed upset when Jeffy ruined the pencil cake Chef Pee Pee made for him in Jeffy's Birthday!.

Rosalina
Jeffy and Rosalina seem to get along well, especially on Rosalina's side. Jeffy usually calls Rosalina "Mommy" just like how he calls Mario "Daddy". Rosalina acts like a deep motherly figure to Jeffy, to the point of sometimes caring more about Jeffy, and calling Mario out whenever he abuses Jeffy. In Jeffy Gets Potty Trained!, though, it is implied that Rosalina is slowly becoming almost as frustrated with him as Mario, as Jeffy refused to eat his peas, demanding marshmallows instead.

Brooklyn T. Guy
As a cop, Brooklyn doesn't seem to mind and cares about Jeffy, as shown in episodes such as Mario The Babysitter!, Jeffy's Bad Word!, Jeffy Goes To The Zoo! and Locked Out. However, in the third episode of Who Wants To Be A Millionaire?, Brooklyn as  is shown to get annoyed with Jeffy's behavior.

Bowser Junior
When both Jeffy and Junior met for the first time in Bowser Junior's Game Night 3, Junior called Jeffy awesome for surviving a game of Russian Roulette. Jeffy was indirectly also the reason for Mario and Junior permanently recognizing each other starting from that episode, and also seems to like Junior. As of recently, both Junior and Jeffy seem to get along more, as shown in Shrek The Babysitter! and Smart Jeffy. In Jeffy Loses His Teeth! he accidently knocked one of Jeffy's teeth out and cracked the other one with a T-Ball bat.

Jeffy's Dad
Not much is known about Jeffy's relationship with his dad, though it can be assumed that he was annoyed by Jeffy's stupidity, possibly causing Jeffy to be abandoned and left at Mario's residence. He is mentioned in Bowser Junior's Game Night 3.

Feebee
In Jeffy's Sister!, it was revealed that Jeffy has a sister named Feebee. Jeffy and Feebee are very similar in character, with nearly the exact same traits. They can even communicate to each other through diaper patting, somehow. However, because she has, so far, only appeared in Jeffy's dream, some speculate that because she was not dropped off along with Jeffy, Feebee either possibly never had been dropped off, never existed in the first place, or may probably be even dead.

Reception
Jeffy seems to be the most controversial SML character ever created, and has been panned a lot by many SML fans, including Dabhdude and GamecubeDude300. People truly criticize the fact that he tortures Mario in some videos. People have even suggested that Jeffy should go back with his real parents in a future SML video, getting rid of him permanently (a few have gone even far as to suggest killing him off).

Despite the character's negative reception received so far, other fans have argued that Jeffy's negative reception is mostly due to Jeffy's Bad Word!, in particular, which has gone on to become of the most infamous and controversial SML Movies to date, because of Jeffy saying faggot and annoying Mario for half the video.. They essentially argue that ever since the release of this controversial episode, they automatically reject any episode that has Jeffy in it at all; for example, many fans point out that Jeffy haters complained about Rosalina's Parents! for having Jeffy in it, despite the fact that Jeffy only had about one minute of screen time and was not even the main focus of the episode. Locked Out also fueled Jeffy's negative reception, becoming the most disliked SML video of all time, beating Jeffy's Bad Word! with over 4,000 dislikes. This makes them the two most disliked Jeffy videos.

 * Jeffy is first seen without his helmet in Where's Jeffy?.
 * Jeffy sometimes speaks normally, and sometimes in 3rd person.
