first rule of betting, like others have said, get the ground rules, PERIOD!!!
make sure the bastards got the money, like others have said, he's most likely just trying to make himself look good in front of his friends, thats why he was f#cking with you...
if its just going to be on the TL, and no sq involved, i'm sure you can waste him with a DD 9510 and 3 or so K of power...
my guess is this is never going to happen or he won't pay you even when you win...honestly you're messing with a JL fanatic who's an idiot...so don't waste your time...cus he won't pay anyways...
