A man goes to visit his elderly father in a care home, and is shocked to see a nurse giving him a large glass of whiskey and a Viagra tablet
"What the hell do you think you're doing" he shouts.
"We do this every night" says the nurse.
"He's 94 years old. Are you mad? What are you giving him whiskey and Viagra for anyway?"
"Well the whiskey helps him to get off to sleep" says the nurse
"And the Viagra?"
"That's just to stop him rolling out of bed.."
