I don't really have to worry, since my own dad, a 50+ year old, watches Nickelodeon and Cartoon Network! I've had friends (in their late 20s) who watch and quote Family Guy and the Simpsons, among other shows, and even enjoy the Tick or Dungeons & Dragons marathons. The only time I come across this problem is comments made on a TV show, or when I listen in on someone's conversation. I'm free to enjoy cartoons, and would anyway.
