A man is sitting next to a woman on a jet that is about to take off. Suddenly, the man sneezes. He unzips his pants and wipes himself off with his handkerchief. He zips up, and continues reading his magazine.
The woman cannot believe what she has just seen. Then he sneezes again, unzips, and wipes himself off again with the handkerchief.

The woman says, "Excuse me, sir, but that's disgusting and rude! If you do it again, I'm going to call the flight attendant and have you removed from this plane."

He says, "I'm so sorry that I've offended you. I have this very rare, embarrassing physical handicap that causes me to orgasm every time I sneeze."

The woman, disarmed by the man's honesty, and somewhat embarrassed by her own callousness, says with sympathy, "Oh you poor man, what are you taking for it?"

"Pepper," he answers.
