This is a special Christmas episode: JKX-mas! Jamie, complete with a scarf and a pipe, is accompanied on the set by pianist Greg O'Connor, who normally composes the incidental music for the series. First, Jamie plays a Santa who uses a photo studio as the place to get his Claus on with some hot mommies! How far will an unsuspecting elf let him go, especially when a vengeful husband stops by for a visit?

Secondly, Jamie gets TV personality Jillian Barberie to host a charity banquet for the homeless. As a priest, Jamie tests the morals of a man who pretended to be homeless just to get a free meal! WB reporter Mindy Burbano appears as herself.

Finally, Jamie and Jeff Goldblum audition models to advertise a new cologne called "Simply Jeff Goldblum", but what will they do when they learn, in Jeff's absence, that the cologne is toxic?
