1) The most powerful force in the world is that of a disc
straining to land under a car, just out of reach (this
force is technically termed "car suck").
2) Never precede any maneuver by a comment more predictive
than "Watch this!"
3) The probability of a Frisbee hitting something is directly
proportional to the cost of hitting it. For instance, a
Frisbee will always head directly towards a policeman or
a little old lady rather than the beat up Chevy.
4) Your best throw happens when no one is watching; when the
cute girl you've been trying to impress is watching, the
Frisbee will invariably bounce out of your hand or hit you
in the head and knock you silly.
