Clark Griswald: I think you’re all fucked in the head. We’re ten hours from the fucking fun park and you want to bail out. Well I’ll tell you something. This is no longer a vacation. It’s a quest. It’s a quest for fun. You’re gonna have fun, and I’m gonna have fun… We’re all gonna have so much fucking fun we’re gonna need plastic surgery to remove our goddamn smiles! You’ll be whistling ‘Zip-A-Dee Doo-Dah’ out of your assholes! I must be crazy! I’m on a pilgrimage to see a moose. Praise Marty Moose! Holy Shit!

Rusty Griswold: [Grabs Clark’s shoulder] Dad, you want an aspirin?

Clark Griswald: Don’t touch!
