Copperhead Tattooing in Louisiana is running a surprisingly popular promotion with a gumball machine that spits out random, meaningless tattoo designs for $40.

Brave customers wanting to get a mystery tattoo put quarters into the repurposed machine and turn the crank. Like the sign says, they "get what you get". It costs fifty cents to get the design and then another $40 to get the ink put on your skin, which is pretty cheap for a tattoo. For another $10, customers can respin and get another design.
