A man and a woman were seated next to each other in the first class section of an airplane.
The woman sneezed, took out a tissue, gently wiped her nose, then visibly shuddered for ten to fifteen seconds.
The man went back to his reading. A few minutes later, the woman sneezed again, took a tissue, wiped her nose,then shuddered violently once more.
Assuming that the woman might have a cold, the man was still curious about the shuddering. A few more minutes passed when the woman sneezed yet again. As before, she took a tissue, wiped her nose, her body shaking even more than before.
Unable to restrain his curiosity, the man turned to the woman and said, “I couldn’t help but notice that you’ve sneezed three times, wiped your nose and then shuddered violently. Are you OK?”
“I am sorry if I disturbed you, I have a very rare medical condition; whenever I sneeze I have an orgasm.”
The man, more than a bit embarrassed, was still curious.
“I have never heard of that condition before,” he said.
“Are you taking anything for it?”
The woman nodded, and replied …
….
…..
Yes, “Pepper.”

You deserve a double ‘like it’ click for this one, I’ve just shuddered violently; with laughter 🙂 🙂
Lol. 🙂
Zen, the joke I remember was that of an elderly man who went to the doctor to complain that every time he sneezed he got an erection. The doctor asked him had he been taking anything for it, and the guy replied “snuff”.
