From the youtube description:
"Meet the Spy, one of nine playable character classes in Team Fortress 2. He is deadly—handsome, that is. But mostly deadly. He is a puzzle, wrapped in an enigma, shrouded in riddles, lovingly sprinkled with intrigue, express mailed to Mystery, Alaska, and LOOK OUT BEHIND YOU! but it is too late. You’re dead. For he is the Spy—globetrotting rogue, lady killer (metaphorically) and mankiller (for real).
First video of Meet the Spy on YouTube. Enjoy."
