Hot Chocolate and Viagra

A man goes to visit his 85-year-old grandpa in the hospital.

"How are you feeling grandpa?" he asks.

"Fine, Fine, just fine," says the old man.

"How's the food?" the young man asks.

"Terrific, wonderful menus, couldn't be better," adds the old timer.

"How are the nurses treating you?" the concerned grandson inquires.

"Great, these young nurses really take care of me." grandpa adds.

"What about your sleeping? Are you still having trouble sleeping?" again concerned about his grandad's response.

"No, Problem! 9 hours solid sleep 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 for the night."

Scratching his head and very puzzled and confused the grandson rushes off to question the nurse in charge.

"What are you people doing? he says. "I'm told my 85-year-old grandpa gets Viagra on a daily basis. Surely this isn't true?"

The nurse smiles politely. "Yes, at 10 o'clock every night we bring him a cup of hot chocolate and a Viagra tablet. It works quite well. The hot chocolate makes him sleep all night and the Viagra stops him from rolling out of bed."
