depends- maybe the men have to stop to go to the bathroom, or they don't friggin feel like eating that many pies!!!!!! sheesh!
ok, i feel better now. if 1 and a half men eat 1 and a half pies in 1 and a half minutes. 3 men can eat 3 pies in 1 and a half minute since we want to know how many they'll finish in half an hour, multiply it by 20, because 20 x 1.5= 30, so i get 60
... but that's wrong
