Grandma and Grandpa were visiting
their kids overnight.
 
When Grandpa found a bottle of Viagra in
his son's medicine cabinet, he asked
about using one of the pills.
 
The son said, "I don't think you should
take one Dad; 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 still like to
try one, and before we leave in the
morning, I'll put the money
under the pillow."
 
Later the next morning, the son found
$110 under the pillow. He called
Grandpa and said, "I told
you each pill was
$10, not $110.
 
"I know," said Grandpa. "The
hundred is from Grandma!"
