VII. Certain bodies can pass through solid walls painted to resemble tunnel
entrances; others cannot.
This trompe l'oeil inconsistency has baffled generations, but at least
it is known that whoever paints an entrance on a wall's surface to
trick an opponent will be unable to pursue him into this theoretical
space. The painter is flattened against the wall when he attempts to
follow into the painting. This is ultimately a problem of art, not
VIII. Any violent rearrangement of feline matter is impermanent.
Cartoon cats possess even more deaths than the traditional nine lives
might comfortably afford. They can be decimated, spliced, splayed,
accordion-pleated, spindled, or disassembled, but they cannot be
destroyed. After a few moments of blinking self pity, they reinflate,
elongate, snap back, or solidify.
IX. For every vengeance there is an equal and opposite revengeance.
This is the one law of animated cartoon motion that also applies to
the physical world at large. For that reason, we need the relief of
watching it happen to a duck instead.
X. Everything falls faster than an anvil.
Examples too numerous to mention from the Roadrunner cartoons.
