I saw this video making its way around Facebook this afternoon, and I found myself laughing along with him!

Last night, he was trying to poke some fun at Gerard Depardieu, the actor that decided to... uh... relieve himself on a plane.

But, after only a couple of bad puns, Cooper totally lost his composure.

And, trust me, 40 seconds may not be that long... But when you're on the air, it seems like an eternity!

Best line? While trying to stop the laughter, Cooper says, "This has actually never happened to me. You always see this sort of this on YouTube, but never think it will actually happen to you."
