The interesting thing is how much the Simpson's are a part of our culture. "DOH!" is uttered in my house on a daily basis. "HaHa" pretty often as well.
Because of the movie, they seem to be even more in your face. I "Simpsonized" myself today, and here is what I would look like if I were in the Simpson's. Our church has a message using the Simpson's this weekend (our Sr. Pastor is simpsonized on the website). Burger King commercials with Krusty are very funny and are everywhere. It's one heck of a machine.
By the way, what exactly is a Spiderpig?
