Sportsman's Double

I ended up with an older woman at a club last night. She looked okay for a
57-year-old.

We drank a bit, and a had a bit of a snoggle and she asked if I'd ever had a
Sportsman's Double.

"What's that?" I asked.

"It a mother and daughter threesome," she said.

I said, "No."

We drank a bit more, then she says that tonight was my lucky night.

I went back to her place.

She put on the hall light and shouted upstairs: "Mum, you still awake?"
