A woman in London was walking in the park with her house guest, a member of a Roman Catholic religious order.
Unfortunately one of the city’s many pigeons dropped its calling card on the visitor while flying overhead.
“Oh, I’m terribly sorry!” the embarrassed Londoner said to her guest.
“Not to worry,” the good-humored sister replied as she dabbed with her handkerchief at the dropping on her habit. “It’s quite obvious that that pigeon was on a nun-stop flight.”
