“Rude Removal” is a season two episode of Dexter's Laboratory that initially didn't air because of salty language. A lot of salty language. More than 15 years later, however, it aired on Adult Swim. In the episode, Dexter invents a machine that removes the rudeness personality trait, but when Dexter and Dee Dee separate from the rude versions of themselves, they must deal with the extremely mean counterparts. Seriously, there are f-bombs being dropped and just foul language galore that would've been too much for 1997, even if the whole thing were chock full of bleeps.
