			I can have a 100% that a coin will come up heads 100 times in a row just buy a two headed coin.
		
		
	 
The advantage move is this:  flip a two headed coin in the air and say, "Call it for $100!" If the person calls tails, let it fall, pick it up and collect.  If the person call tails, catch it in midair and declare, "No bet.  I was just kidding!"  lol
Scratch the term "advantage" and replace it with "cheating."    lol
The above scenario is strictly hypothetical. Injury may result in real life.
