I was a little hesitant to go to the movie after seeing the trailer - it looked like one of those slapstick comedies where the whole movie is really in the trailer. I was wrong. My girlfriend and I laughed till we wheezed. They did a good job of keeping a connective sub-plot alive in every scene, plus a lot of the scenes were actually ad libbed by these great comedians, so it felt fresh and funny rather than predictable and slap stick.
