Could he be a little-known athlete? A Russian sports journalist? An obscure model?

Whoever he is, he has a gigantic cardboard cutout that athletes are posing for pictures with in an Olympic Village cafeteria as part of a bizarre mini-meme from Sochi.

He does look a little bit like Bruins' player and Slovakia hockey captain Zdeno Chara, though the resemblance isn't convincing.

If anyone can identify this sweatshirted man, stop what you're doing and contact ABC News immediately.
