“What?” (Lone Starr)
“I am your father's brother's nephew's cousin's former roommate.”
“What's that make us?”
“Absolutely nothing! Which is what you are about to become.”

“I'm a mog: half man, half dog. I'm my own best friend!” (Barf)

“So, Lone Star, now you see that evil will always triumph because good is dumb.” (Dark Helmet)

“So the combination is... one, two, three, four, five? That's the stupidest combination I've ever heard in my life! The kind of thing an idiot would have on his luggage!” (Dark Helmet)
