My friend was always teasing me about cybersex and trying
to lead me on.  One day he wrote a really racy letter so I 
decided to "call his bluff".  Forgetting I'd deleted his letter
out of  habit, I accidently responded to my Recipe Du Jour list
instead  and wrote:  "Thanks a lot.  Now I can't get any work
done.  My panties are wet from the anticipation of your next
email."  A gentleman wrote back:   "Sorry, I didn't realize
salsa had such an effect."
