Michael and Jay go out for the evening without reciting "the rules" to Claire. That means it's party time, and the party animal turns out to be Claire's usually pious boyfriend Tony.

Tony returns from a "purification exile" that followed his drunk-and-naked escapade, and Michael finds condoms in Claire's backpack. Naturally, he suspects linkage. Meanwhile, Jr. and Vanessa get a dog---a male they name "Lady"---as a "dress rehearsal" for parenthood. Jr. will soon demonstrate just how much rehearsal he'll need.
