Wacky that as of 26 votes, heads/tails is 50/50.
		
		
	 
what's interesting, is that I chose Scissors for the same reason you chose Paper.
See, I'm gambling that most often people will think... "hmm, a lot of people open with rock, so I'll open with paper." The death's on them, cuz they gettin cut! 
 
And heads. No particular reason here. Unlike rock paper scissors, where there is a minimalist strategy, heads/tails is completely random. I actually most often choose tails for coin flips, but no real reason.
