After Novak Djokovic knocked off Roger Federer and won his third Wimbledon title, he did something strange. He knelt to the ground and plucked a blade of grass. Then, he ate the grass.

Afterwards, he called it his "tradition" and explained that as a kid he always dreamed of winning Wimbledon and doing "something crazy" to celebrate it.

So, he did it.

"It tasted very very good this year," Djokovic said in a television interview. "I don't know what the grounds people have done, but they've done a great job."

Hopefully the grass was gluten free.
