Michael must deal with a huge mole problem in order to salvage a major real estate deal with Japanese investors. In an effort to help Michael, Gob and Buster (Tony Hale) team up with George Sr.'s surrogate, Larry (guest star Bob Einstein), to devise a plan and save the deal, but their plan falls apart in a big way. Meanwhile, Tobias (David Cross) mistakes a CIA agent for a CAA agent and inadvertently betrays the family, and Michael makes Rita a proposal she can't refuse. Frankie Muniz makes a cameo as himself.
