This episode was so funny. The were parts that were just outloud laughing no matter what! First, Jack and Karen were instructed by Will to keep Grace busy for a while on the day of her birthday. So, one funny part was when Karen walks out of Jack's apartment, and says Happy Birthday to Grace while Jack comes up behind her and covers her head. Also, when Jack and Karen have made and set it so Leo wouldn't show, it was funny. I was laughing very hard when Grace said, "You threw him out of a car!". That was hilarious. There were many lines that were funny and I love this episode. It is one of the better ones in season 5.
