Bud Light: "Rock, Paper, Scissors"
Two guys fighting over the last Bud Light at a cookout. They decide to play Rock, Paper, Scissors to see who gets it. Guy on the left throws paper, guy on the right throws a rock. He really throws a rock, and knocks the other guy out and takes the last Bud Light. One of the other partygoers calls the police and the guy is arrested for assault.
OK, that last part I made up. Funny commercial I guess, though I really don't know if Bud Light is worth getting violent over. Sam Adams? Definitely.
