Video prankster Jack Jones approaches unsuspecting victims on the streets of London and he might ask them for a kiss, tickle their neck or just give them a simple high five to put a smile on their faces.

The 21-year-old has built up a Facebook following of over 1 million people and his dream is to get his own pranking TV show.

On a recent trip to American things got a bit hairy though.

When trying out his ‘Get Into a Stranger's Car’ stunt on a random stranger things went badly wrong - and he had a gun pulled on him.

Jack jump into the strangers car and told the burly man: “Hello my friend I have come here to work and clean the car.”

Jack Jones quickly regretted this prank as a gun was pulled on him

But the prank went terribly wrong when the man became aggressive and pulled out a gun.

The unidentified man raged: “You get the f-off my car” before Jack fled the scene, screaming: “Mate it's a joke, it's joke”.

During other pranks he has been punched and attacked in the street by members of the public.

It's not all bad though. Over the past two weeks Jack has been feeding the homeless whilst filming their reaction, hoping this will inspire others.

On Mother's Day, Jack purchased over 250 red roses and walked the streets of London handing them out to the elderly.
