Grandma and Grandpa

Grandma and Grandpa were driving from Washington to Florida to attend their granddaughters graduation from medical school.

Halfway through their trip, they stopped to visit one of their sons in Kansas for a night. Grandpa found a bottle of Viagra in the medicine cabinet. He asked his son 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. "Around $10.00 a pill," answered the son.

I don't care," said Grandpa, "I'd still like to try one, we'll be leaving early in the morning, so I'll put the money under the pillow."

Later the next morning, the son found $110.00 under the pillow. He immediately called Grandpa on his cell phone and said, "I told you each pill was $10.00, not $110.00.

"I know," said Grandpa. "The hundred is from Grandma."
