Plot summary
The crew are set to cater a birthday party for actor Steve Guttenberg at his house, but when he shows up, he tells them his friends already threw him a surprise party the previous night. He ends up inviting the Party Down crew in his house for a party and tells them to invite any friends. Ron returns as an improved man after entering into AA. Kyle invites Colette, a girl from his acting class, hoping to hook up with her. Roman invites his writing partner Kent ( Christopher Mintz-Plasse ), where they are working on a script.
Guttenberg suggests that they act out their screenplay, to get a better perspective on the material. After finishing a scene, everyone suggests it needs more emotion, leading Kent and Roman to rewrite it, much to Roman's dismay. When reacting out the scene, it leads to Henry and Casey kissing. Later when both in the jacuzzi, Casey kisses him again, but Henry holds back, because he has a girlfriend. Casey then leaves. At the end of party, everyone leaves, although Colette stays behind with Steve Guttenberg, leaving Kyle behind on the way out the door.
