A man and a woman are sitting beside each other in the first class section of the plane. The woman sneezes, takes out a tissue, gently wipes her nose. Then she suddenly begins to shudder violently in her seat.

The man isn’t sure what's going on, so goes back to reading. A few minutes later the woman sneezes again. She grabs a tissue, gently wipes her nose and once again begins to shudder violently.

The man is becoming more and more intrigued with this shuddering thing. A few more minutes pass and sure enough she sneezes yet again. So, out comes a tissue and after a gentle wipe the shuddering starts up.

The man has finally had all he can take. So he turns to the woman and says, "Three times you’ve sneezed and three times you’ve taken a tissue and wiped your nose then you shudder violently! Are you sending me signals or what?"

The woman replies, "I’m sorry if I disturbed you. I have a rare condition and when I sneeze, I have an orgasm." Now the guy is feeling a little embarrassed but is even more curious. He says, "I’ve never heard of that before. What are you taking for it?"

The woman looks at him and says, "Pepper."
