Plumber Guy

Plumber Guy should be Brooklyn Guy’s grandfather, and the dad of Barbara. Brooklyn Guy only called Plumber Guy his dad because Barbara and Mr. Guy probably divorced when Brooklyn was at very young age, and to cover it up, she got her dad to act as Brooklyn Guy’s father. Until Plumber Guy died, Brooklyn, Barbara, and Jonathan were at his funeral (maybe Debra or Brooklyn Guy’s first ex too) and Brooklyn Guy heard the Minister say that Barbara was his daughter. Then Brooklyn Guy found out. And that’s why he knows about his real dad, Mr. Guy.

Ok, hear this out doofy the dragon was made and aired in the 1900s. The reason I know this fact was because on one episode of doofy the dragon. This episode of DTD it shows "plumber guy" (Brooklyn guy's dad) who has supposedly died in 1993 which shows that at least to things are wrong the date of the plumber guy dying is wrong or doofy the dragon was aired before 1993!
