This is the most hardcore of the hardcore. I am not impressed with your wacky-pants tattoos of cupcakes or cartons of menthol cigarettes or whatever else your little hipster-Dada heart dreams up. Getting a tattoo of a neuron is officially the only thing that will get props from me. Plus, you gotta earn your science tattoo. Don't get the solar system unless you can at least name all the planets in order, starting with the closest to the sun. Thanks.
