From the NYPD, to Australia, to the tiny Isles of Scilly off the coast of Cornwall - police stations around the world have been responding to the challenge of a dance-off.
The first video of a performance was posted by New Zealand Police on Tuesday - and now it's the turn of Police Scotland to put their own spin on the "Running Man Challenge". And what better backdrop than Edinburgh Castle... complete with bagpipes, of course.
Who knew Scottish police had such epic dance moves in them?
FYI, the challenge has been passed on next to London's Metropolitan Police, Toronto and also the Police Scotland colleges.
Bring on more of the Running Man.
