If you're Roger Federer, how do you kick off your 29th birthday celebrations?
By having Sidney Crosby deliver a cake, of course.
Crosby played the role of delivery boy Sunday after a practice session with the tennis star in Toronto was called off because of rain. The Penguins superstar could have been celebrating his own birthday, though, after turning 23 on Saturday.
Even though they didn't get to hit the ball around, Crosby and Federer had a chance to shoot the breeze about a variety of sports topics, including the former's gold-medal win at the Olympics.
