There’s a banned Dexter’s Laboratory episode where Dexter makes a machine meant to remove the rudeness of Dee Dee but they both end up accidentally getting into it and making two rude clones of themselves (w/ stereotypical New York accents) who cuss and swear throughout the entire episode.

It’s called Rude Removal and was originally made and meant to air in 1998 as a part of Season 2, but didn’t for obvious reasons. It was released uncut on Adult Swim’s website in 2013, and you can watch the uncensored version here (click) !
