Heads or Tails

This one is a bit, well…basic.  Buy your entry fee, and the game begins!
The MC will toss a coin, and you will either put your hands on your head or your butt.  Simple as that!
Guess right, and you move on to the next round.
Guess wrong, and you're out.  Continuing to hold your butt is optional at this point.
Rounds will continue until just one player remains sheepishly holding a body part.
Winner gets a fun prize!
