(The scene begins with three players on their hands and knees, in a row, like bicycles.)
Shop Owner: Well, there we are, three brand new bicycles all set up for sale.
Customer : (Entering) Hi. I'd like to buy a bicycle. Shop Owner: Sure thing. Why don't you try them on for size? (Customer sits on the first bike and it falls down. The second is too big, while the third is too small.)
Customer: I sure like the first one, let me try it again.
Shop Owner: Why not? (Setting up the bike again) There you are, it's all set up again. (Customer sits on it, and again it falls down.)
Customer: I don't know. I really like this one but it keeps falling down. I'm afraid it's not made well enough.
Shop Owner: Our bicycles are all very well made. It was just assembled this morning, and it may need a little adjustment. Let me get some help.
(A volunteer is chosen from the audience, who is instructed to hold one 'wheel' of the now upright bicycle.)
Customer : (Sitting on the bike) That's perfect now. What was the problem?
Shop Owner: Oh, we just need a big nut to hold it together!
