(The scene begins with three players on their hands and knees, in a row, as 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 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!
