Strategy guide:
Get a load of fat kids. They all stand in a line, one of them throws the ball backwards and then they all run head first into a load of other kids and fight in a big lump. The kid who gets the ball should be able to throw, preferably not like a girl. Lots of fast kids shoudl run around in front and catch the ball when the other guy throws it. OIther kids are likely to run into them or knock them over. Dust everyone off and repeat.
