Grandpa & Grandma were visiting their
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.
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
it and I'll leave the money under your pillow
as soon as I break this $50.00 bill."
The next morning the son found $110.00
under his pillow. He said to Grandpa, "I told
you each pill was $10.00, not $110.00."
"I know, the extra hundred is from your grandma."
