Everyone needs to lighten up. I like Sarah, I think part of her standup is funny. The joke isn't that she's using the word retarded, the joke is the utter ridiculousness of her approaching an adoption agency and saying, "please give me your most retarded baby, but I also want them to be terminally ill."

Maybe I'm insensitive or too immature, but that makes me laugh like crazy. Just imaging the look on the adoption agency person's face is hilarious.

Here's a similar clip of Evil Dave Letterman from the Howard Stern show calling an adoption agency asking for a black kid: http://www.youtube.com/watch?v=bXrhI2q-EeI
