“I do a million of these a day, so just gimme five,” he says.

The Vine video was posted in response to first lady Michelle Obama’s #GimmeFive challenge.

The first lady is asking Americans to share five things they’re doing to lead a healthier life to commemorate the fifth anniversary of "Let's Move!"

Celebrities have taken the first lady up on the challenge, too.
