Some dumb laws are really dumb they take your breath away. Here are some examples in the land of Saguaro cacti, where I spent three years of my irretrievable life.
In Arizona:
Hunting camels is prohibited.
There is a possible 25 years in prison for cutting down a cactus.
When being attacked by a criminal or burglar, you may only protect yourself with the same weapon that the other person posseses.
You may not have more than two dildos in a house.
It is illegal for men and women over the age of 18 to have less than one missing tooth visible when smiling.
Not bad, eh? I'll take a better look at these examples from other US states.
