Friday Puzzle

I've taken this Friday puzzle directly from "Futility Closet" earlier in the week. It assumes familiarity with the game "rock, paper, scissors":

"Andy and Bob play rock-paper-scissors 10 times. Andy plays 3 rocks, 6 scissors, and 1 paper (in some order), and Bob plays 2 rocks, 4 scissors, and 4 paper. There are no ties. Who wins?"

...This reminds me that you can play computerized 'rock-paper-scissors' online at this NY Times site (...but please don't do it while driving ;-):
