A Google search on “cartoon laws” will yield an abundant plethora of links to lists of “Cartoon Laws of Physics”. Most of these lists contain the same entries with a few variants and additions added here and there. Perhaps we can come up with some of our own that have not been included in most of these lists. I’ll provide a link to the original list for reference. Here are mine:
Any time an antagonist is navigating a river, whether it be via boat, floating log or barrel, there will always be a steep waterfall just ahead. If said antagonist is successful in reversing his direction of travel, an identical waterfall in the opposite direction will also appear.
Any time an antagonist finds himself on a railroad a train will inevitably appear at that very moment.
Boats, ships and other watercraft always sink directly and instantaneously into the body of water on which they are traveling.
Power lines are extremely elastic. This is best demonstrated by having an antagonist projected into the path of said power lines, where his body’s forward movement will stretch the lines to their limit, before catapulting him back in the opposite direction in which he came.
Sound can be contained in the hands, maintaining volume and pitch, until released far from someone that must not be waken.
Protagonist will always be unaware he has been shot until drinking a glass of water, at which point the water streams out of bullet holes.
Exposure to electricity will generate X-ray fields around protagonist, rendering the skeleton visible.
A cliff ledge will always break just at the point at where the antagonist stands. This will invoke the law which states that antagonists will remain suspended in midair until such time that they notice they are suspended in midair.
Any technology, advanced or otherwise will work perfectly for the protagonists but refuse to function, or explode, when used by the antagonists.
**Cartoon animals will always triumph over their human opponents. **
A villain trying to escape from the hero can take cars, trains, planes, rocket ships only to find, when he arrives at his destination (and securely locking the door of his chosen refuge) that the hero is in the same room with him.
Arrogance displayed by anybody, either good or bad, always meets it’s comeuppance.
An antagonist will always have their larger portion of the tree/building/whatever fall when they cut/saw/blow up a portion of it, leaving the protagonist safely perched in mid-air.
A cut down tree always falls on the antagonist’s head no matter what precautions are taken.
Holes are portable.
Paint opens a dimensional portal usable only one time.
Acme will forever remain in business despite offering inferior products.
Running into a chain link fence will always neatly cut a character into dozens of neat diamond shapes, which can be repaired by moving off screen momentarily.
All characters are required to have a closet full of extra skin/feather suits.
Some characters getting hit on the head make a sound very similiar to percussive instruments.
Male animals are attracted to human females. Human females are also a very easy disguise to make, and are indistinguishable from a real human female even when worn by an animal (until, of course, the wig slides off and the rabbit ears are revealed).
The prey outwits the predator in every circumstance. Scientists are still puzzled how predators have managed to avoid extinction.
No living soul has ever managed to successfully complete playing the song “Those Endearing Young Charms.”
