A few years back I was in a pub chatting with an older lady at the bar.

She asked if I wanted to go home with her. I politely declined, as she was at least 60.

She asked if I had ever been with a mother and daughter, and if I was interested?

Sounded promising, so I went to her house and as we walked in the door she yelled up the stairs ...
"Mam, get up and put yer teeth in, we've got company!"
