This photo isn't so much a head-scratcher as it is a leg-scratcher.

This picture of a man holding up a prosthetic leg popped up on Reddit on Monday, along with a comment reading, "This guy really wanted a Mavs t-shirt last night."

Presumably, the fella was at a Dallas Mavericks game, but we don't know for sure if he was using the appendage to procure a shirt that was being thrown into a crowd by a slingshot, although it does appear the game was in a timeout, which is usually when those PR stunts take place.

For all we know, he was trying to get the attention of a beer vendor or practicing ways to distract the visiting team when they lined up for free throws.

If he was trying to get a T-shirt, though, and failed, well, you can bet he was hopping mad.
