So, uh … what?

The Baysox, Double-A affiliate of the nearby Orioles, hosted "Back Hair Appreciation Night" on Thursday, forgoing more mainstream promotions like food or "Back to the Future" and providing free professional grooming services to four lucky (?) fans. Yep.

So, in case you've always wondered what it looks like when someone gets his back waxed live during a baseball game ...

Now you know.

And hey, the Baysox did end up winning the game, 4-3. Maybe for the rest of the season, they'll only score as many runs as the number of backs that are waxed during each game. Now that would be a promotion.
