my sister has a little skin-colored bump on her ear here (that's not her ear, i'm just pointing out where it is, this ear DOES NOT HAVE THIS, i know what a regular ear looks like). it sticks out a tiny bit from the rest of the skin. it's round with like a millimeter diameter. we always assumed it was a birthmark. cool, whatever.
my friend was leaning over me to get something last week and i realized he has the same exact thing. same bump on the ear.
