LOL! This was so priceless that I'll give you a little preview...
Jab: Elbow & Pawnch
For this move, Bill uses his right arm. First he makes a fist in front of his chest, pointing outwards with his elbow. He grabs the fist with his left hand and uses the power of his left arm to give the first attack more momentum. He then rams - similar to Ganondorf's Forward Smash - his elbow into anyone who could be around. If you press the button again, his left hand will let lose of his right. Then he punches with the back of his fist (his elbow still is out there!) into the face of his victim. This all sounds insanely complex, I know, but actually that all happens very quickly. He has no infinite, after those two hits - which both do very low knockback and 2-3% damage each - you will have to press the buttons again. But since the move is very quick, it still isn't that stupid, right?
