Are cartoons really just for kids?

We’ve all heard the urban legends about the phallic symbol snuck onto the label of Disney’s Little Mermaid, and the sex scene hidden in the clouds in the Lion King. I was just wondering how many other things fly under our ‘radar’ when we let our kids sit to watch cartoons.

I was just watching an old episode of Woody Woodpecker with a neighbor kid, and there is a reference to opium smoking in it. (watch the video. It’s on the list of rules Wally the Walrus shows Woody.) This made me wonder how many other things we think are innocent enough actually have hidden innuendos not meant for children.

Does anyone have any examples you’d care to share? Why do you think the cartoon makers do this?
