Perhaps not appropriate when we honour a truely great human but I found this very funny when I saw it...

She was debating at Oxford or some such (PBS TV show I saw years ago) and she said something about a young girl (5 years old) at a family picnic seeing young Johnny standing while peeing at the edge of the woods and this was the first realization the little girl had that Johnny had different set of equipment. From the upper gallery, a young man shouted, "Is that why they call them Picnicers?"

Again, *I* found it a hilarious, perhaps because of the situation and the spontaneity. Your mileage may vary.
