Cartoons are made for kids, but they’re made by adults — adults who understand that parents make up a good deal of their audience. Because of that, a lot of animators bury sexual innuendos, drug references, dirty one-liners or other adult-themed jokes within the spit-shined world of their shows. Sometimes subtle, sometimes not, the jokes are intentionally crafted to fly over kids’ heads and kerplunk into the ears of older viewers. And there are more than you might think. SpongeBob SquarePants is once caught watching sea anemone porn; the grandpa on Hey Arnold! talks about getting baked; hell, even Rugrats got in on the action. Here, for your viewing pleasure are 50 very adult jokes shoehorned into classic kid’s cartoons.
