Ok, guys I warned you so if you continue to read - it's your own fault. I
know some of you don't like jokes. But this is from a woman point of view.
Enjoy.

Grandpa and Grandma were visiting the kids overnight, when Grandpa found
a bottle of Viagra in his son's medicine cabinet. He asked the son about
using one of the pills, and the son said "I  don't think you should take
one; they're very strong and very expensive." "How much?" asked Grandpa.
"$10.00 a pill," answered the son.   "I
don't care," said Grandpa, "I'd like to try one, and I'll leave the money
under your pillow as soon as I break this $50.00 bill."

Next morning the son found $110.00 under his pillow. He called and said
to Grandpa, "I told you each pill was $10.00,  not $110.00."  "I
know," said Grandpa. "The hundred is from Grandma."
