The gang is catering the birthday party of a fictionalized version of Steve Guttenberg. The setting is intimate: a small gathering of friends at "The Gute’s" modest but comfortable home. Unlike the high-stakes, high-anxiety events of previous episodes (like the mob daughter's wedding or the sweet sixteen), the vibe here is surprisingly chill. Guttenberg plays himself as a benevolent, slightly desperate, and overly enthusiastic host who just wants everyone to relax and swim.

Roman DeBeers (Martin Starr) and his writing partner Kent (Christopher Mintz-Plasse) are forced to workshop their "hard sci-fi" script with Guttenberg. The clash between Roman’s cynical intellectualism and Guttenberg’s "actor-y" enthusiasm provides the episode's funniest moments.
