Conan O’Brien, Michelle Obama #GimmeFive Challenge: Kevin Hart Helps TBS Host Cheat at Chin-Up Contest

Who said CONAN host Conan O'Brien couldn't do chin-ups? All he needs is a little motivation, a challenge... and comedian Kevin Hart. To celebrate the fifth anniversary of her Let's Move! campaign – which aims at helping children live healthy lifestyles and fight childhood obesity – First Lady of the United States Michelle Obama decided to create the #GimmeFive challenge. Much like the ALS Ice Bucket Challenge, this contest has a person challenge another to do five somethings (chin-ups, jumping jacks – something that makes them move.) When (and if) they complete it, that person is then required to pass on the challenge. Which is exactly what O'Brien did after accepting Obama's chin-up challenge. Of course, he did have some help...

"Hey Conan, can you believe it's the fifth anniversary of Let's Move?" says the FLOTUS in the below video. "Now, I've been watching you on TV for a long time, and I haven't noticed much muscle on those arms."

Therefore, in order to honor the fifth anniversary, Obama called O'Brien out, challenging him to do five chin-ups. And, well, he accepted... kind of.

.@FLOTUS Your #gimmefive challenge has been accepted - 11 PM 2nite on TBS (I’d write more, but my arms cramped while typing this tweet).

Not too bad ... for someone on the shoulders of another man.

Alright, Bill Nye – the challenge goes to you! Are you up for it?
