I got told this by my old boss who came round randomly to say hi. (friend of my father)

A man and a woman are sitting next to each other on a plane. During the flight, the woman closes her eyes, holds a handkerchief to her nose and sneezes. Afterwards, she shudders heavily.

Then it happens again: She sneezes into the handkerchief... then shudders violently. The man raises an eyebrow. When it happens a third time, the man gives into his curiosity and speaks.

"I couldn't help but notice that you shudder violently after every time you sneeze."

The woman blushes a little and replies,

"Well... I have this strange condition, where whenever I sneeze, I have an orgasm."

The man looks rather embarassed.

"O-oh! I see... are you taking anything for it?"

She nods with a giggle.

"Pepper!"
