If there weren't pictures to prove that it happened, I'm not sure I would have believed it. What you see above is Minnesota Timberwolves point guard Marko Jaric attempting to enter the game with his jersey on backwards.
Now, I can't tell you that I've never put a shirt on backwards before. But then again, I own very few shirts with my name on them. My best guess at what happened here is that Wolves head coach told Marko Jaric that the name of the front of the jersey was more important than the name on the back ... and Marko thought to himself, "Well, I guess we'll have to do something about that."
