The normally uber-professional Anderson Cooper gets a major case of the giggles as he cracks a joke about Gerard Depardieu on The Ridiculist. He urinated on an Air France plane in front of other passengers after flight attendants told him he could not use the restroom.

The joke was something like Gerard Depard-do-do.

Proof that even when they are grown and very straight-laced and proper…boys will always think poop is funny.
