Dexter's Labatory was a classic cartoon produced for Cartoon Network in the late 90s, and a new series again in the early 2000's, featuring boy genius Dexter whose hobbyist projects were often interfered with by his older sister Deedee. During the original run, urban legend had it that there was an episode produced that was too profane to be aired. It was more than likely produced for the production team's own amusement and was never intended to air. Similar things have happened before such as the infamous episode of children's show Rainbow, about "Twangers". As it turns out, this episode is very real, as [Adult Swim] have premièred the episode on their YouTube channel. The basis of the episode is that Dexter creates a rude removal machine, that extract someone's rudeness leaving them very polite and well mannered. The flipside is that it also produces an incredibly rude and ill-mannered duplicate. Rude Dexter and Deedee are extremely liberal with their profanity, so there's a heck of a lot of *bleeps* Funnily enough, another Cartoon Network show, The Powerpuff Girls actually did a similar episode with heavy bleeping called "Curses", where the girls accidentally learn a dirty word when Professor Utonium burns his hand, and deal with a literal potty mouthed monster at the end. This episode actually was aired as normal, though apparently the censored words were not profane at all.
