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 $110.00 under the pillow.
