Sneezing Joke

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 ever time she sneezes she has an orgasm!
Oh! The man said, are you taking anything for it?

Yes,she said ---- black pepper!!!!
