PBJ

"so lets imagine you're going to put peanut butter on two pieces of bread, for a PBJ sandwich. okay but, the catch is that you're only going to get one swipe of the knife in the peanut butter jar - imagining you have both a knife and a jar big enough for this - you'll have to try and dig out the exact right amount of peanut butter for both of your pieces of bread; the whole sandwich. You get one swipe, no putting any back, no grabbing any more. You got me? So the real question is, are you the kind of person that scoops out too much peanut butter, or not enough?"

"what the fuck are you talking about."
