It is against the law to have a sleeping donkey in your bathtub after 7 pm.

In Arizona, this law was brought into effect due to a public menace case in 1924. A merchant used to allow his donkey to sleep in a bathtub. The town was flooded when a local dam broke and the donkey was washed a mile down the valley. The donkey survived, but locals spent a lot of time and manpower to save the animal. This law was passed shortly afterwards.
