Way back when I was in the Army (early ‘90s), a blonde, female SFC in my unit went to sick call after having a dizziness episode. No lie, when she told the medic about it, his first response was “dye your hair”. She was more than a little ticked when she got back to the unit.
I know of a brunette who went to the doctor and complained that no matter WHERE she touched herself she experienced excruciating pain. Doctor said “Nah, can’t happen.” She proceeded to use her index finger to touch her breast, her butt, her stomach and her shoulder,and screamed loudly and agonizingly. Doc ruminated on this for a while and asked “You are not a true brunette, are you?” She answered No, I’m a blonde. Doctor looked at her and said “You have a broken finger.”
