Robot Chicken

Luke Skywalker:
Your overconfidence is your weakness.

Emperor Palpatine:
Your faith in your friends is yours!

Luke Skywalker:
[chuckle; whisper] Faith in yo' mama.

Emperor Palpatine:
What was that?!

Luke Skywalker:
I said, yo' mama so fat, Jabba the Hutt said, "DAAAAMN!"

Emperor Palpatine:
Well, your mother's so ugly, she put the "Ug" in Ugnaught!

Darth Vader:
Aww, yo' mama fight!

[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]

Crowd:
Oooohh!

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]

Crowd:
Ohhh!

Luke Skywalker:
Yo' mama so dumb, she thought Jar-Jar, comes with "Pickles-Pickles"! [Vader gives Luke another point]

Crowd:
Oooh!

Emperor Palpatine:
Your mother is so stupid, she.. she thinks a lightsaber has fewer calories! [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]

Luke Skywalker:
And 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!
