Who is Chris Putnam?
Chris Putnam is a Facebook engineer who became instantly infamous due to the ":putnam:" Facebook emoticon created as a joke by a friend.
The story, as Putnam tells it, is that he's a very thin guy, and around 5 or 6 years ago he decided to try to cram himself in a freezer, the type that's on the top of a refrigerator (He offers no details about why; if it was a dare, or just a joke...)
He goes on to say that a photo of him was taken "with my head sticking out of the freezer, flush with blood from my contorting, and it's one of the worst photos ever taken of me."
Matt Cahill, apparently another FaceBook Engineer, decided to hand create an icon from that photo and coded it into the FaceBook chat software. The emoticon is summoned by typing ":putnam:" in the chat.
