"I don't think you should take one of those," says the grandson when his grandpa asks him about them: "They're pretty expensive."
"How much?" asks the old timer.
"$20 a pill," replies the grandson.
"I'd still like to try one," says the old man: "Before we go in the morning I'll leave the money under the pillow in the guest room."

"I know," says the old man: "The extra $100 is from your grandma!"
