Much of the movie takes place in "the little van that could." It's fun watching the characters deal with each other as they traverse the desert in a vehicle resembling a sardine can.
Naturally, fights break out. We particularly liked the exchanges between Greg Kinnear (Richard) & Steve Carell (Frank).
FROM THE SCRIPT:
Richard:
"I just want you to know -- I feel sorry for you."
Frank:
"You do? Good."
Richard:
"Because sarcasm is the refuge of losers."
Frank:
"It is?! Really?!"
Richard:
"Sarcasm is just the sour grapes of losers trying to pull winners down to their level. Step Four."
Frank:
"Wow, Richard! You've really opened my eyes to what a loser I am! Say, how much do I owe you for those pearls of wisdom?"
Richard:
"It's on me, buddy. It's on me."
Sheryl:
"Okay, you guys, enough. Frank, stop it."
Frank (pointing):
"He started it!"

"He started it!"
heh heh heh!
