How does Alex Trebek do it? 

Alex Trebek didn't hesitate when he shut this contestant down after the contestant responded with a very inappropriate answer to a question. When answering the question "In common law, the age of this, when signaling adulthood, is presumed to be 14 in boys and 12 in girls" one of the contestants fervourously answered "What is the age of consent?" Before the audience, and Chris Hansen, could process what just occurred, Alex Trebek did what he did best and moved on with a fleeting "No." As for the contestant, we're sure he's somewhere in Thailand wondering why he lost that round.
