SOme of these kind remind of of a line from kiss kiss bang bang..
Main character is doing the russian roulette interigation method.. loads the revolver with a bullet, starts yelling at the guy to start talking, then spins it. guy claims doesnt know anything, puts the gun to his head, click, "BANG!"
WHAT THE HELL! WHY DID YOU DO THAT!
That shouldnt have happened! Theres only like a 6 percent chance the bullet was in there!
SIX PERCENT! Where the hell did you get that!!
THere are six Cylinders so a 6 percent chance of it going off!
Where the hell did you learn Math!!
(its along those lines, im probally missing a good bit..)
would work good as an interrigation method.. have 2 guys or more, doit on the guy you know knows nothing, then say i'll prove it and go to the guy who does know something.. be spilling his gut out with everything he knows.. and probally into his pants some as well.
