Jeffrey Tobias "Jeff" Winger (Joel McHale), is a snarky, glib ex-lawyer attending Greendale Community College.

Jeff was a lawyer until the Colorado Bar Association found out that he did not get a bachelor's degree from Columbia University but, in fact, got one that was "less than legitimate" and "better than real" from the country of Colombia. He returns to college by attending Greendale Community College as a deal with the bar in order to prevent him from being disbarred. He consequently hopes to graduate as quickly as possible.

Donald "Don" Draper is a fictional character and the protagonist of AMC's television series Mad Men. He is portrayed by 2008 Golden Globe winner Jon Hamm. Until the third season finale, Draper was Creative Director of Manhattan advertising firm Sterling Cooper. He became a founding partner at a new firm, Sterling Cooper Draper Pryce, after he and his superiors abandoned their old agency in advance of an unwanted acquisition.

Draper's character is partially based on Draper Daniels, the creative head of the Leo Burnett advertising agency in Chicago in the 1950s who created the Marlboro Man campaign. However, some of the advertising techniques and the professional accomplishments of Don Draper are based on those of Rosser Reeves, who rose to chairman of the Ted Bates agency.

In 2009, the fictional Draper was named the most influential man in the world by Ask Men, ahead of real-life figures.

Most of the characters in the series know little, if anything, of Draper’s history and true identity; Harry Crane remarks in the third episode of the series, "Draper? Who knows anything about that guy? No one’s ever lifted that rock. He could be Batman for all we know." Clues are given through flashbacks, confessions, and clandestine visits to figures from his past.
