The US Olympic women's Rugby team was facing world #1 Australia in the final game of pool play and Kathryn Johnson decided to set the tone early.  19 seconds into the match, she dropped her own banhammer on the team from down under.  Team USA rallied around Johnson and managed a 12-12 draw in the match, only to lose to World #2 (New Zeland) in the next round.

The US didn't make the medal round, but its safe to say they'll be remembered by at least one player.  (Spielman was not impressed)
