Grandpa found a bottle of power tablets

Grandpa and Grandma were visiting the kids overnight, when Grandpa found a bottle of Man power tablets 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.”

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,” said Grandpa.

“The hundred is from Grandma.”
