My attempt to create a counterpart to The Cartoon Laws of Physics
. So far I've got:
1. The male and female of a non-human species that does not walk upright on two legs can be distinguished because the female possesses long eyelashes and the male doesn't. (Example: Santa's Little Helper and She's The Fastest in the Simpsons episode Two Dozen and One Greyhounds)
2. The male and female of a non-human species that does walk upright on two legs can be distinguished by the female's eyelashes and/or breasts, or the female always choosing to wear a dress. (Eyelashes: Minnie Mouse vs. Mickey Mouse; breasts and eyelashes: Bugs Bunny when dressing up as a female vs. his usual self; dress: Dot Warner vs. Yakko and Wakko, her brothers)
3.Coyotes and cats are impervious to being squashed and most other types of wounds.
4. Most animals are not able to recognize their own species when looking for a mate (Pepe Le Pew and Penelope the Cat; Bugs Bunny's dressing up as a human female and a Tasmanian Devil female and fooling males of those species)
More ideas are welcome.
