This is a really funny episode, I couldn't stop laughing in the pool scene, a pool table in a small room is a brilliant idea.All the sub-plots were amazing in this episode. Susan's roommate from collage was really funny and stupid, and she ruined Jerry's material to the Charles Grodin show twice. This episode contains a lot of George, maybe that's why it's so funny. And all the nagging about Jerry's material was hilarious.
The doll was creepy, and the end when Frank Costanza destroys the doll was great too.
Season 7 is a really good season, and this is the best episode in it.
