Cartoon Law I:Any body suspended in space will remain inspace until made aware of its situation.

Cartoon Law II:Any body in motion will tend to remain inmotion until solid matter intervenes suddenly.

Cartoon Law III:Any body passing through solid matter willleave a perforation conforming to its perimeter.

Cartoon Law IV: The time required for an object to falltwenty stories is greater than or equal to the time it takes

for whoever knocked it off the ledge to spiral down twentyflights to attempt to capture it unbroken.

Cartoon Law V:All principles of gravity are negated by fear.

Cartoon Law VI:As speed increases, objects can be in severalplaces at once.

Cartoon Law VII: Certain bodies can pass through solid wallspainted to resemble tunnel entrances; others cannot.

Cartoon Law VIII:Any violent rearrangement of felinematter is impermanent.

Cartoon Law IX: Everything falls faster than an anvil.

Cartoon Law X: For every vengeance there is an equal andopposite revengeance.
