[Darth Vader stands by a chalkboard to keep score while making a piece of chalk levitate with the Force; Luke and Emperor Palpatine stand on opposite sides from each other]
Luke Skywalker: Yo' mama so stupid, she spent all day saying, "am not!" to R2! [Vader gives Luke a point]
Emperor Palpatine: Your mother is so fat that Ben Kenobi said, "that's no moon, [gets up in Luke's face] that's yo' mama!" [gets a point from Vader]
Luke Skywalker: Yo' mama so dumb, she thought Jar-Jar, comes with "Pickles-Pickles"! [Vader gives Luke another point]
Emperor Palpatine: Your mother is so stupid, she.. she thinks a lightsaber has fewer calories! [record needle scratch followed by silence; Palpatine acts as if he'll get a big, positive reaction but doesn't; Darth Vader shakes his head in disgrace]
Guy in Crowd: Huh? I don't get it.
Emperor Palpatine: It's "lite"... like, it's "lite," like calories... like, "lite" means there's not a lot of calories and it's good.... for your body, that's how stupid your mother is. [does not earn a point]
Luke Skywalker: Yo' mama so stupid, she went to Bangkok to get a TIE Fighter! [receives another point]
[the crowd cheers]
Another Guy in Crowd: Luke wins!
[Darth Vader lifts Emperor Palpatine over his head and walks him over to a ledge]
Emperor Palpatine: What are you doing? Wh-what are you doing?! P-put me down! N-no! [Vader tosses Palpatine over the ledge] AAAHHHHHH!
