A man in London tried – that being the operative word – to sail down a subway escalator one night.

It didn’t go very well.

A video spreading online shows the apparently 30-year-old man attempting to slide down the rail of the long escalator before falling off and crashing on his back.

He was clutching a beer in one hand and being goaded on by rowdy onlookers who were laughing hysterically.

A London transportation official has slammed the people in the video, saying that “pranks like this are dangerous for not only those involved but also to other customers.”

The clip was posted by the daredevil’s friend David Bailey, who told The Daily Mail this week that “it was a real spur-of-the-moment thing.”

“We were all shocked he did it, but couldn’t help laughing,” he said.

“Not the best idea we’ve ever had.”

The man was later treated at the first-aid station for his injuries – but apparently, was still able to make it out that night.
