Here are a couple “Yo Momma So Fat” jokes (geeky style) that came out of a conversation with my 11 year old.  If you are easily offended by “Yo Momma” jokes, then don’t read this post.

• Megatron’s Momma so fat that when she transforms, she turns into a DUMP TRUCK!
• Darth Vader’s Momma so fat, they call her butt THE DARK SIDE!

These remind me of the Robot Chicken: Star Wars episode:

Luke Skywalker: Your overconfidence is your weakness.

Palpatine: Your faith in your friends is yours.

Luke Skywalker: Not my faith in yo momma…

Palpatine: What was that?

Luke Skywalker: I said yo momma’s so fat, Jabba the Hutt said DAAAAAMN!

Palpatine: Well, your mother is so ugly she put the ‘ug’ in ‘ugnaught!’

Darth Vader: Ohh, yo momma fight!

[Cut to next scene. Luke and Palpatine are on stage in front of a crowd]

Luke Skywalker: Yo momma’s so stupid, she spent all day saying ‘am not’ to R2!

Palpatine: Your mother is so fat, that Ben Kenobi said ‘That’s no moon, that’s yo momma!’

Luke Skywalker: Yo momma’s so stupid, she thought Jar Jar came with pickles pickles!

Palpatine: Your mother is so stupid she, she thinks, uh, that lightsabres come with fewer calories!

[Music cuts. Crowd falls silent]

Palpatine: You know, cause it’s ‘lite,’ and it’s got less calories… and it’s good for your body, ummm… anyway that’s how stupid your mother is…

Luke Skywalker: Yo momma’s so stupid she went to Bangkok to get a TIE fighter!

Crowd: Luke wins!

[Darth Vader throws Palpatine into the reactor core]
