Speaking of Big Trouble in Little China quotes that make GREAT battlecries, here's a few:
"Son of a bitch must pay!"
"I'm gonna tell you about an accident, and I don't wanna hear 'act of God'!"
"6.9 on the Richter scale!"
"I can see things no one else can see. Why're you dressed like that?"
"This is gonna take crackerjack timing!"
