Mark Callan has been to three previous Winter Olympics
Did you hear about the 61-year-old from Glasgow who's been captured moonwalking down the curling rink at the Winter Olympics?
Mark Callan shakes his head and laughs. It's been quite a week or so for the Scot, who has been plastered all over various social media platforms in the course of doing his job.
You might well have seen Callan. He is the guy with the back pack and hose, shuffling backwards down the sheet inside the near-empty Cortina Curling Stadium, spraying plumes of water into the air. Pebbling the ice, it's called.
Some clips have been set to music, exaggerating his dainty movements. Parodies have appeared. One broadcaster from Norway, amid peals of laughter, described the chief ice technician as "scooting" down the sheet.
