A tip:

If you want to have a really hilarious time at a party, go to a party where almost everyone in attendance is in a sketch or improv comedy group. You may not fit in, but you will laugh your ass off. We did Mad Libs as a party game, going around the circle to fill in the blanks. It's a really terrific party game, actually, but I'll bet it's even better when the people who read the end result are trained in keeping straight faces.
