— "Don't you hate when people talk loudly on their phones in public?" asks professional prankster Greg Benson.

Benson, of MediocreFilms, believes he's come up with the perfect way to get people to stop having loud private conversations on their cellphones when they're out in public.

He calls his technique "cellphone crashing," and it's exactly what it sounds like.

In his latest candid camera video (shot by his wife), Benson situates himself next to chatty cellphone users at the airport, and proceeds to pretend he and the person next to him are having identical conversations.

Simple yet diabolical yet harmless yet effective. The best kind of trolling.
