- This article is about the character Mark Hamill. For the voice actor, please see Mark Hamill.
Mayor Quimby introduced Hamill to the Sci-Fi Con crowd as "Luke Skywalker himself, Mark Hamill!" to the glee of the assembled nerds. They quickly got annoyed and impatient, however, when Hamill repeatedly made sales pitches for Sprint instead of talking about Star Wars.
When Hamill said that he was going to act out a scene from Star Wars and asked for a volunteer to play the part of Obi-Wan Kenobi, a crowd of would-be volunteers rushed onto the stage and a riot quickly ensued. Hamill apparently twisted his ankle, but Homer Simpson came to the rescue, carrying Hamill out of the con and also clearing the way for Mayor Quimby to escape. Hamill was grateful for the rescue, and the experience motivated Homer to become a professional bodyguard. Homer ended up taking on the job of protecting Mayor Quimby when Quimby fired his own bodyguards due to their ineffectiveness during the nerd riot.
Hamill appeared in the Springfield Dinner Theater's production of the musical play Guys and Dolls, playing the role of Nathan Detroit. Over Hamill's objections, the producers had him doing the part as Luke Skywalker, dressed in Luke's Tatooine outfit, carrying his lightsaber, and singing "Luke, Be a Jedi" instead of "Luck, Be a Lady". When Louie was pressed into service to do a solo dance number, Hamill accused Louie of stealing Hamill's share of the spotlight and the two of them got into a fight.
It turned out, however, that Louie's real purpose for being at the dinner theatre was to assassinate the mayor. Hamill helped Homer to spoil Lenny's attempt, telling him to "Use the forks!" to take Lenny's knife away and pin him to the table (through his tie). However, Fat Tony succeeded in getting to Quimby and beating him with a baseball bat.
When the play was over, Hamill had Homer help him make his escape by carrying him through another crowd of fans.
