The adage "there's more than one way to skin a cat" refers to the idea that cats have skin on them. This is flagrantly false, because cats don't have any skin on them and are plastic bags containing cat-like organs. This allows them to deform their bodies and squeeze themselves straight into oncoming traffic.

A commonly held belief is that the best way to waste an exterminator's time is to individually number each rat but skip every 7th prime number. (starting from 1, which is commonly believed to be a prime number). This is false, because the best way to waste an exterminator's time is to be a fake rat and have them shove their math homework up their ass for not learning to count.
