Ok, here is an update with all of the ideas loosely compiled. Some of the quotes may not be exactly right, but since I'll just be using the ones from the actual movie, its not important.
Keep the ideas coming, I've got some hardware on the way to go ahead and set up a development rig for this thing. I'll post some pics once I have something to show.
Specific movie concepts:
Ludicrous speed/They've gone plaid
Combing the desert - We ain't found shit!
All of the assholes
President scroob's reversed ass from the transporter
Pizza the hut
You went over my helmet?!
Fuck! Even in the future nothing works!
Radar - Bleeps, Creeps, Sweeps
Build warp speeds up to ludicrous speed
Mega Maid multiball - She's gone from suck to blow!
Marketing madness where specific actions earn a piece of spaceballs merch
Lighting up false jackpot shots with a "FOOLED YOU" callout
Grand Champion is possibly renamed to Major Asshole, the other levels could be Gunners First Mate, etc...
Ball Save - Keep Firing assholes or May the schwartz be with you.
Cradle the ball too long, prince Valium yawns
1-2-3-4-5 targets for luggage combination
Match sequence could be luggage combination
Tilt callout: Why dont we take a 5 minute break, smoke if you got'em!
Callout: Why didnt somebody tell me my ass was so big
Callout: Are you playing with your dolls again
Callout: Get back here you fat bearded bitch!
Callout: What's the matter, Colonel Sandurz? CHICKEN?
Callout: Oh shit, there goes the planet
Callout: I Told you we should have put more than 5 bucks worth in
Attract Mode: long ship flyby with dramatic opening music
Attract Mode: Spaceballs: The Pin logo with "We're the spaceballs" theme music.
