A man and woman were sitting beside each other in the first class section of the plane. the woman sneezed, took out a tissue, gently wiped her nose and then shuddered quite violently for 10 or 15 seconds. Tha man went back to reading. A few minutes later, the woman sneezed again, took a tissue, gently wiped her nose and shuddered quite violently as before. The man was becoming more and curious about the shuddering. A few more minutes passed and the woman sneezed one more time. Again she took a tissue, gently wiped her nose and shuddered violently.
The man couldn't restrain his curiosity. He turned to the woman and said "You've sneezed three times, wiped your nose with a tissue, then shuddered violently! Are you alright?"
"I'm sorry if I disturbed you" the woman replied. "I have a rare condition, when I sneeze I have an orgasm".
The man was a little embarrassed but even more curious and said "I've never heard of that before. What are you taking for it?"
The woman looked at him and said "Pepper".
