Grandma and Grandpa were visiting their kids overnight. When Grandpa discovered a bottle of V pills in his son’s medicine cabinet, he was curious and asked about trying one.

The son hesitated and said, “I don’t think you should, Dad. They’re very strong and really expensive.”

“How much?” Grandpa asked.

“$10.00 a pill,” the son replied.

“I don’t care,” Grandpa said, determined. “I’d still like to try one, and before we leave in the morning, I’ll put the money under the pillow.”

The next morning, the son discovered $110 under the pillow. Confused, he called Grandpa.

“Dad, I told you each pill was $10, not $110,” he said.

“I know,” Grandpa replied, chuckling. “The extra $100 is from Grandma.”
