If you are from Douglass Kansas, then WalleyBall is when you take a volleyball sized ball (the plastic WalMart balls work fine) and hit it onto the roof of the house (on the Wall).? The other person then tries to figure out where it is coming down and hits it back up "on the Wall (the roof).? Point when it doesn't get returned.? Obviously, hard to play in NYC with three story buildings.

In civilization, it's volleyball played in a racquetball court with the net across the middle of the court.? Hitting the ball off the walls is allowed, which is the feature that makes it the most fun.

I'll bet you wouldn't be awful at it, you have to be a little athletic in order to ski.  If you played stickball or any of those hand/eye coordination games, then it wouldn't be that tough.? What you might lack in skill you can make up with conditioning and enthusiasm.
