UGO does a good job in compiling lists and can be compared to Cracked.com. Which is a humungous compliment to them. They’ve listed a couple of movies of where kid’s movies have adult innuendos. Not all kids movies are strictly for kids. There are a couple of jokes that simply fly over their heads and the parents and baby sitters put their hands over their mouths and giggles. Here’s the link.

I grew up reading Mad and Cracked. The lists are great!
