Anderson Cooper, who broke into a giggle fit while delivering a pun-filled monologue on the Ridiculist about Gerard Depardieu's reported urination on the cabin floor of an airplane this week, appeared to surprise even himself with the force of his reaction.
In Anderson Cooper’s case, the reported tinkling prompted the giggling. More often, it’s the giggling that prompts the tinkling, an event known as giggle incontinence. And yes, this is a real medical condition. Though it's not well understood, it appears to occur when the detrusor muscle, which squeezes urine from the bladder, contracts during a fit of laughter.
