Jack "Danny" Baker (Cheyenne Jackson) is a Canadian singer and former robot street performer whose silver paint caused memory loss problems. He had to change his name from Jack to Danny because Jack Donaghey did not like sharing a name with Baker. Baker was hired on the show after being the only person in New York who would take the elevator with Jack Donaghey after learning that he had bed bugs. He had a brief romance with Liz which Jack Donaghey disapproved of and eventually ended the not serious relationship. By the end season 5, Jack "Danny" Baker succumbs to Josh Girard's memories.
