Sneezing On A Plane

A man got on a plane and sat next to a blonde, after sitting for awhile she sneezed, took out a tissue and whipped her box. The man not knowing her said nothing and went about his business. After about 3 or 4 minutes she sneezed again and, the same thing, whipped her box. Finally, the man got the nerve and asked:

- what was wrong?

She said that every time she sneezes she has an orgasm.

- Oh! - the man said, are you taking anything for it?

- Yes - she said - black pepper!
