A man and a woman are riding next to each other in first class on a plane. The woman sneezes, then takes a tissue¹ and gently wipes it between her legs. The man isn't sure he saw what she did, and decides he is probably hallucinating.

A few minutes pass. The woman sneezes again. She takes a tissue and gently wipes it between her legs. The man is about to go nuts. He can't believe that he's seeing what she's doing. A few more minutes pass. The woman sneezes yet again. She takes a tissue and gently wipes it between her legs yet again. The man has finally had all he can handle.

He turns to the woman and says, "Three times you've sneezed, and three times you've taken a tissue and wiped it between your legs! What kind of signals² are you sending me, or are you just trying to drive me crazy?"

The woman replies, " I am sorry to have disturbed you, sir. I have a rare³ condition such that when I sneeze, I have an orgasm."

The man, now feeling bad, says, "Oh, I'm sorry. What are you taking for it?"

"Pepper⁴", she replies.
