Federer takes questions from group of second graders

Roger Federer faced his toughest crew of reporters yet when a group of local second graders threw down their best questions at the BNP Paribas Open press room.

When asked for his coolest move, Federer tried to describe a tweener to the awe-struck children.

"Maybe the shot through the legs," Federer said. "It's like... I'm facing you guys as the opponents. You hit a ball over my head and I have to run [backwards] and then I hit it through the legs, and it comes back to you. And I've hit a few good ones."

The 35-year-old has hit way more than "a few good ones." Since there's too many to count, here's this one on a rooftop last year and this classic tweener lob at Wimbledon two years ago.

Other questions from the unabashed reporters included lighthearted ones like "How much chocolate is in Switzerland?" as well as deadly serious ones like, "How old do you want to be when you stop playing tennis?"

"I hope I'm going to be 90 years old," Federer said, before revealing a more realistic five years.

Before the press conference was over, Federer was on the ground for some group pushups, surely a first in his lengthy media career.
