This article is about the character Mark Hamill. For the voice actor, please see Mark Hamill.

Mark Hamill is an American actor most famous for his role as Luke Skywalker in Star Wars. He appeared as a speaker at the Springfield Bi-Mon-Sci-Fi-Con.

Mayor Quimby introduces Hamill to the Sci-Fi Con crowd as "Luke Skywalker himself, Mark Hamill!" to the glee of the assembled nerds. They quickly get annoyed and impatient, however, when Hamill repeatedly makes sales pitches for Sprint instead of talking about Star Wars.

When Hamill says they're going to act out a scene from Star Wars and asks for a volunteer to play the part of Obi-Wan Kenobi, a crowd of would-be volunteers rushes the stage and a riot quickly ensues. Hamill apparently hurts his knee, but Homer Simpson comes to the rescue, carrying Hamill out of the room and also clearing the way for Mayor Quimby to escape. Hamill is grateful for the rescue, and the experience motivates Homer to become a professional bodyguard. Homer ends up taking on the job of protecting Mayor Quimby when Quimby fires his own bodyguards due to their ineffectiveness during the nerd riot.

Hamill appears in a dinner theatre production of the musical play Guys and Dolls, playing the role of Nathan Detroit. Over Hamill's objections, the producers have him doing the part as Luke Skywalker, dressed in Luke's farmer outfit, carrying his lightsaber, and singing "Luke Be a Jedi Tonight" instead of "Luck Be a Lady Tonight." In attendance at the theatre are Mayor Quimby, guarded by Homer, and Fat Tony. While attempting to assent the mayor, Fat Tony's henchman Louie is forced into a dance number on stage. Hamill, not to be upstaged, hostilely reminds him whose headshot are featured next to the pepper steak.

Hamill then helps Homer to spoil Louie's attempt, telling him to "Use the forks!" to take Louie's knife away and pin him to the table (through his tie). However, Fat Tony succeeds in getting to Quimby and beating him with a baseball bat.

When the play is over, Hamill has Homer help him make his escape by carrying him through another crowd of fans.
