"After a night of drinking, my friend thought it would be a good idea to go down the escalator with his bicycle," says YouTube user Pr0uditalian, posting the above footage shot at the Pacific City shopping mall in Huntington Beach, California.
As the video shows, it wasn't so much the ride down the escalator that caused his pal to come to grief - rather that no-one had employed sufficient foresight to work out he'd head straight into a glass wall when he got there.
Not one to try at home ... or indeed at the Trafford Centre, Bluewater, Westfield Stratford City or whatever your local shopping centre happens to be.
