Benjamin rushes to his doctor.
"Doctor, you've got to give me something to make me young again. I've got a date with this beautiful young girl tonight."
His doctor said, "Hold on a second, you're 70 years old, there's really not a lot I can do for you."
Benjamin replies, "But doctor, my friend Tony is much older than I am and he says he has sex three times a week."
"OK," says the doctor, "so you say it too!"
