If you've been trolling the internet at all in the last few days, you've seen "Ball Girl," a YouTube video showing a ball girl making a brilliant catch of a foul ball by climbing the wall. The catch with the catch is that it's all fake, just a viral advertising campaign for Gatorade.
That said, it's pretty good.
There are REAL catches by ball girls and ball boys out there. Spend a minute or two hunting and you will be amazed.
