Here's Mikhail Youzhny at the Miami Masters tournament facing off against Spaniard Nicolas Almagro. After ending a long point with an unforced error into the net, Youzhny reacts like any real competitor would: by beating himself in the head with his racket until he opens up a bloody gash [Heh... "bloody gash" - Ed.]. The tactic worked well for Youzhny, as he rallied for seven consecutive points after the incident on his way to victory.
Is this the single best intimidation tactic I've seen in ages? To borrow the words of a fatter man, fuck and yes. Andy Roddick could be a world champion if, after losing a point, he'd pull out a hunting knife and slowly give himself a long cut down the cheek, then return to the court with a wild look in his eyes. That dilettante Federer would crap his pants. Instead, Roddick's a little coward who needs to preserve his pretty-boy looks so he can chase swimsuit models. What an idiot.
