Watch This Hilarious Cell Phone Crasher Prank

A guy who does prank videos on YouTube has a new one, where he sits down next to people at the airport while they're talking loudly on their cell phone.  Meanwhile, he's on his cell phone, but he starts responding to everything they say.

It takes most of the people 10 or 20 seconds to figure out what's going on.  But then when they ask what he's doing, he acts like they're interrupting his call.

I am going to try this the next time I fly somewhere!
