There's a peculiar trend taking place in Olympic photography. Time and time again, pictures of athletes biting down on their medals filling up blogs, newspaper and Twitter feeds.
It's not just U.S. athletes who are sinking their teeth into bronze, silver or gold — Olympians from all over the world are captured in this very pose, which leaves us wondering: Why?
We genuinely don't know why this is occurring. Perhaps it's at the request of photographers, but again: Why?
Whatever the reason, it doesn't look like Olympians are going to let up on the ol' medal-chewing anytime soon. With about two more days before the closing ceremony, there are probably plenty more chomp photos to be taken.
Mmmm, victory. Nom nom nom nom.....
