cheesy but...
A man is sitting next to a woman on a jet which is getting ready to take off. Suddenly, the man sneezes. He unzips his pants and wipes the end of his penis off with his handkerchief. He zips up, and continues reading his magazine.
The woman cannot believe what she just saw. Then he sneezes again, unzips, pulls out his penis and wipes it off with a handkerchief.
The woman says, "Excuse me sir, but that is disgusting and rude, and if you do it again, I am going to call the flight attendant and have you removed from this plane.
He says, "I am so sorry that I have offended you. I have this very rare, embarrassing physical handicap that causes me to have an 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.
