Dirty Grandpa Harry was feeling a bit frisky one night. Not wanting to waste a rare erection he nudged Grandma laying in bed next to him.
“Hey Ethel,” he said as he lifted the sheets. “How’d you like to put your teeth around this beauty!”
Bleary eyed she reached over to the nightstand and grabbed her dentures. As she handed them to Harry, she said, “You go right ahead, but try not to disturb me.”
