(I have psoriasis, a hereditary condition which leaves me with large red patches on my scalp. This occurs while I am waiting in line at a convenience store with a woman standing behind me.)
Customer: "What’s wrong with you?"
Me: "I beg your pardon?"
Customer: "Those ugly blotches all over your head. What do you have?"
Me: "Oh, it’s a highly contagious flesh eating disease. Very painful."
Customer: "Oh my gosh! Really? How contagious is it?"
Me: "Well, you probably already have it."
Customer: *rushes out of the store in a panic*
