Race car drivers play game with marshmallows

It's a game as old as marshmallows and usually played by elementary school kids, but who doesn't love a good round of Chubby Bunny?

It's the one where people stuff as many marshmallows as possible into their mouths while still coherently saying "chubby bunny," and Team Penske's NASCAR and IndyCar drivers took a stab at it for Round 2 of the Penske Games. (They assembled toy race cars for Round 1.)

While tremendously juvenile, the game still provides some good laughs, including from the drivers.

NASCAR drivers Joey Logano forfeited, Brad Keselowski tried stuffing a handful of marshmallows in his mouth at once and, totally unable to contain his laughter, youngster Ryan Blaney reminds us that he was probably playing this game in school just 10 years ago.
