A man goes to the nursing home to visit his eighty-four-year-old father.
While there he notices the nurse hand his father a cup of hot chocolate and a Viagra pill.
The man asks the nurse, “Why are you doing that?
At his age, what will either do for him?”
“The hot chocolate,” the nurse explains, “will help him fall asleep faster.”
“All right,” the man replies, “and what about the Viagra?”
“That keeps him from rolling out of bed.”
