Penguins' Kessel is all jokes in behind-the-scenes video

He may be all business on the ice, but off it, Phil Kessel is quite the jokester.

The Pittsburgh Penguins released the first episode of their behind-the-scenes series "In The Room" where Kessel immediately stole the show with his constant wisecracks during the team's media day.

Kessel admitted - sarcastically - he's a "wonderful singer" and then came to the harsh realization that he might be balding. Luckily, he can still score goals.

And win Stanley Cups.
