An amusing video has emerged of a man, who appears to be drunk, struggling to stay upright outside a pub in east London.

33 year old Barnaby Slater was with a big group of friends celebrating a birthday in a Hackney pub garden when he caught the footage of the stranger struggling to walk forwards on his mobile phone camera.

“I was in a pub garden for a friend’s birthday party, saw the guy over the road and immediately started filming. The man just couldn’t walk forwards, every time he thought he walking properly he was actually stumbling backwards, that’s why I had to film it.”

With the stumbling man falling over backwards, someone can be heard on camera shout, “drugs are bad”. With a seemingly invisible force field not allowing him to move forwards, he shuffles forwards then backwards for a staggering 2 minutes before he eventually gives up an opts to lie down.

“This was the strangest thing I’d seen in a long time, he must be on something strong! After I finished filming I got back to enjoying the party.”

Although the video was captured in July, it has only recently emerged online.
