When Dennis Duffy (Dean Winters), Liz's ex-boyfriend, becomes New York's latest local celebrity, Jack books him to appear on TGS. Dennis tries to win Liz back into his life.

When Jack rejects him, he befriends Kenneth, who happens to be a fan. Instead of Bucky, Jack tries to convince Tracy to become the celebrity face of the Republican Party.
