Well with me the biggest example would not be any of those three, it is a TV called "Little People, Big World" on TLC about a family with two LP parents, Matt and Amy Roloff, and one LP son, Zack Roloff.
Honestly I never had much understanding of what an LPs life is like until I started watching that show. I somehow knew they didn't do everything different, but I didn't have a really solid comprehension of how similar they were to everyone else. That and I grew more respect for them and pretty much stopped using the word "midget".
Nothing really shakes my understanding of someone who is different in a way than that show has. It's frickin' entertaining too!
Other than that I really can't think of much. There are more things although I've never really seen a play, but if I think harder I could probably come up with a movie or song.
