triumph of a raconteur called horse

Dinner with the Murphys.
The noble Heelers is holding forth.
"I was sitting in the Tearman cafe with a friend," quoth I, "and I asked her did she believe in God. And she paused and then said: Yes, yes, I do believe in God. And right that moment a beautiful blue butterfly flew down from the rafters and landed on the lip of her cup. We both stared at it. It flew over to the window and fluttered there beside us for a few minutes. Then it flew off. What do you think that means?"
"It means," said Tom Murphy, "that the Tearman is a very unhygienic cafe. The place is full of feckin butterflies."
