You know those Land O Lakes butter packets, with the little Indian girl on them? Well, get the paper (not the tub) carts, and cut out the Indian girl. Carefully, with a razor, cut out the butter she's holding. Now cut off half her body, and put her knees in place of her butter (behind the first sheet). SEE HOW FUNNY THAT WAS?!?! SHE HAD BOOBI1EX!
Here i found a guy who explained the pinkie thing better:
Lock your pinkies together and pull apart. No problem eh? Now bite down pretty hard (hard enough so that it hurts, but not too hard so that you can't hold it there) for about 30 seconds.
Now lock your pinkies and pull apart.
