this is absolutely true-
Locker-room prank of the year:
When Ivan Ljubicic returned from the showers at the Miami Open he was shocked to open his locker door and discover Michael Llodra completely naked.
The Frenchman, who stands over 6ft tall, had somehow squeezed himself into a locker half his height. Ljubicic asked Llodra what he was doing in his locker. "You're winning a lot of matches this year," Llodra replied, "so I'm trying to get some positive energy from you."
