Houston Rockets guard James Harden is known for his scruffy beard, fearless drives to the basket, and incredible scoring prowess. Perhaps in the future he'll add the word "mime" to that group.

Maybe it's muscle memory, maybe it's his sense of humor, maybe it's a ritual, or maybe he just forgot he was by himself on the free throw line. Harden is hardly the first player to high five air, and won't be the last.

Now, if only he could put some make-up on and pretend to run into a wall.
