Adult Jokes in Cartoons

There's something truly brilliant about cartoons especially when you look at the subliminal humour behind most of it. Even though the majority of cartoons are aimed at children, they're always written by adults and that sense of untainted adult humour occasionally 'leaks' out of
into the cartoons.

The earliest yet least subtle example can be found in the 1950's cartoon "Captain Pugwash" who tastefully yet quite amusingly, hires an individual called Master Bates. Of course it may seem inappropriate yet I don't think this is the case. Many parents watch cartoons with their children and as much as cartoons are awesome, the humour can sometimes be cliched and repetitive.
I personally think it's to make the cartoons more enjoyable for the parents who watch them with their kids.

Whether they are subtle and well done or just obviously crude, adult humour has since been present in cartoons for years, here's a few examples:

-Spongebob Squarepants: The "Krusty Krab" restaurant is located in "Bikini Bottom" geddit?

-Hey Arnold: When Arnold reassures his grandfather that he still has a few brain cells, he amusingly replies "No...not since Woodstock" referring to the exceptional amount of drug taking at the festival
(especially LSD)

-Ed, Edd, n' Eddy: In Edd's incredibly strict household which is constantly littered with sticky notes for him to do, one in the bathroom reads out "Don't touch yourself".

-Rocko's Modern Life: When visiting a doctor, the medic possesses the not so subtle name of "Dr. Bendova referring to awkward prostate exams.

So next time a cartoon comes one and you just refute: "That's for kids", give the episode a chance, you might just a catch a glimpse of some unadulterated humour.
