This is an old-school serving drill we used to do growing up. Really great to do if you are going to play Hozel-Rocket at all because of the aiming qualities. Also, it apparently impresses the English lads - their reactions are classic! When messing around with Adam and a couple other people at a local tennis club in London a couple of weekends ago. We attracted a small audience doing this; it tend to make a bit of noise. My mate Evan - one of the suprised guys talking in the backgroud - captured a bit of this on his camera. Actually all three of them in the audio were in on the contest/bet too. Not the best quality and he managed to miss the five in a row I had at one point and only got the last two of that stretch, but I still think it's pretty cool! Enjoy. Oh, Adam is the one who in angrily handing balls to me.
