"Cartoon Laws of Physics" joke

Cartoon Law I
Any body suspended in space will remain in space until made aware of its situation.
Daffy Duck steps off a cliff, expecting further pastureland. He loiters in midair,
soliloquizing flippantly, until he chances to look down. At this point, the familiar
principle of 32 feet per second per second takes over.
Cartoon Law II
Any body in motion will tend to remain in motion until solid matter intervenes suddenly.
Whether shot from a cannon or in hot pursuit on foot, cartoon characters are so absolute in
their momentum that only a telephone pole or an outsize boulder retards their forward
motion absolutely. Sir Isaac Newton called this sudden termination of motion the stooge's
surcease.
Cartoon Law III
Any body passing through solid matter will leave a perforation conforming to its perimeter.
Also called the silhouette of passage, this phenomenon is the speciality of victims of
directed-pressure explosions and of reckless cowards who are so eager to escape that they
exit directly through the wall of a house, leaving a cookie-cutout-perfect hole. The threat
of skunks or matrimony often catalyzes this reaction.
Cartoon Law IV
The time required for an object to fall twenty stories is greater than or equal to the time
it takes for whoever knocked it off the ledge to spiral down twenty flights to attempt to
capture it unbroken.
Such an object is inevitably priceless, the attempt to capture it inevitably unsuccessful.
Cartoon Law V
All principles of gravity are negated by fear.
Psychic forces are sufficient in most bodies for a shock to propel them directly away from
the earth's surface. A spooky noise or an adversary's signature sound will induce motion
upward, usually to the cradle of a chandelier, a treetop, or the crest of a flagpole. The
feet of a character who is running or the wheels of a speeding auto need never touch the
ground, especially when in flight.
Cartoon Law VI
As speed increases, objects can be in several places at once.
This is particularly true of tooth-and-claw fights, in which a character's head may be
glimpsed emerging from the cloud of altercation at several places simultaneously. This
effect is common as well among bodies that are spinning or being throttled.
A wacky character has the option of self-replication only at manic high speeds and may
ricochet off walls to achieve the velocity required.
Cartoon Law 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 of science.
Cartoon Law 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.
Corollary: A cat will assume the shape of its container.
Cartoon Law IX
Everything falls faster than an anvil.
Cartoon Law X
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.
Cartoon Law Amendment A
A sharp object will always propel a character upward.
When poked (usually in the buttocks) with a sharp object (usually a pin), a character will
defy gravity by shooting straight up, with great velocity.
Cartoon Law Amendment B
The laws of object permanence are nullified for "cool" characters.
Characters who are intended to be "cool" can make previously nonexistent objects appear
from behind their backs at will. For instance, the Road Runner can materialize signs to
express himself without speaking.
Cartoon Law Amendment C
Explosive weapons cannot cause fatal injuries.
They merely turn characters temporarily black and smokey.
Cartoon Law Amendment D
Gravity is transmitted by slow-moving waves of large wavelengths.
Their operation can be wittnessed by observing the behavior of a canine suspended over a
large vertical drop. Its feet will begin to fall first, causing its legs to stretch. As the
wave reaches its torso, that part will begin to fall, causing the neck to strech. As the
head begins to fall, tension is released and the canine will resume its regular proportions
until such time as it strikes the ground.
Cartoon Law Amendment E
Dynamite is spontaneously generated in "C-spaces" (spaces in which cartoon laws hold).
The process is analogous to steady-state theories of the universe which postulated that the
tensions involved in maintaining a space would cause the creation of hydrogen from nothing.
Dynamite quanta are quite large (stick sized) and unstable (lit). Such quanta are attracted
to psychic forces generated by feelings of distress in "cool" characters (see Amendment B,
which may be a special case of this law), who are able to use said quanta to their
advantage. One may imagine C-spaces where all matter and energy result from primal masses
of dynamite exploding. A big bang indeed.
