Six or eight weary-looking campers enter the campfire circle, silently circle the campfire once, and sit in a ring around the fire. After a pause, the first camper sighs and says "What a day!" There's another pause for deliberation before the second camper sighs and says, "What a day!", and yet another before the third repeats, and so on around the circle until they reach the last camper. He sighs and says, "Yes sirree!" (or "You betcha", or something similar).
After a long silence, the first camper says in disgust, "If you can't stick to the subject, I'm getting out of here!" Then he rises and leaves the campfire, followed by all the others.
