A visit with Grandpa
A man goes to visit his 85-year-old grandpa in the hospital.
"How are you grandpa?" he asks.
"Feeling fine," says the old man.
"What's the food like?"
"Terrific, wonderful menus."
"And the nursing?"
"Just couldn't be better. These young nurses really take care of you."
"What about sleeping? Do you sleep okay?"
"No problem at all --- nine hours solid every night. At 10 o'clock they bring me a cup of hot chocolate and a Viagra tablet, and that's it. I go out like a light."
The grandson is puzzled and a little alarmed by this, so he rushes off to question the Nurse in charge. "What are you people doing?" he asks. "I'm told you're giving an 85-year-old Viagra on a daily basis. Surely that can't be true?"
"Oh, yes," replies the nurse. "Every night at 10 o'clock we give him a cup of chocolate and a Viagra tablet. It works wonderfully well. The chocolate makes him sleep, and the Viagra stops him from rolling out of bed."
