“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.

Announcing the revolutionary scientific breakthrough – the Turbo Encabulator:

I know it is hard to believe, but some people just could not understand everything communicated in the first video, so some time later, this second video was made so that all could be made clear:

Mary had a little lamb, his feet were black as soot, and everywhere the lamby went, his sooty foot he put.

There was a young man called Fernando, who ate a big plate full of lego, his body went numb and he looked kind of glum, and realised that rhyming just wasn’t his thing.

There was a young lady from York, who fell in a drum with a cork, the policeman who found her was just about to ground her, when she banged out the theme from Star Wars (she had rhyming issues too).

There was a young lady from Swanich, who swallowed a piano from Dulwich – she has serious problems!

There was an old man from Skye, who had an aversion to Pie, he sat on his bed wearing trousers that were red, and then went downstairs and made himself a cup of tea, a ham sandwich with lettuce, with a sprinkle of pepper.

There was a young rodent named Stu, who was highly addicted to glue, he fell to his knees every time that he sneezed, and thankfully, that was the only side effect.
