Anderson Cooper just can't contain his laughter!
The "Anderson Cooper 360" host's giggles got the best of him (again!) last night on his show -- where it got so bad, he actually had to walk off-camera.
The chuckles started during a segment about Dyngus Day, the Polish holiday marking the end of Lent.
Cooper was able to hold himself together until a voice-over describing the holiday's traditions read the words "a tap from a pussy willow branch." From there, it was all over.
Check out the hilarious and adorable video above!
