A rare medical condition...

A man and woman are seated next to each other on a plane. After takeoff - the woman violently sneezes and excuses herself to go to the bathroom - so the man stands up to let her out.

She returns - 15 minutes later she sneezes again big time - and again excuses herself to go to the bathroom.

She returns again and immediately sneezes - excusing herself to go to the bathroom.

The man (a little tired of jumping up so often) asks her: "You keep sneezing, what's the problem?"

The woman replies: "I have a rare condition... every time I sneeze I have an orgasm."

He says, "Oh... what are you taking for it?"

She says: "Pepper." ;)
