She says her late husband wasn't much of a friend of anything other than missionary, she quite fancied trying french style, a bit of 69. So they get themselves positioned on the bed and get down to it.

"Pity about all them people. Real shame that."
"What do you mean? What's the pity?" asks the old woman.
