Need: 3 scouts (2 older scouts and 1 cubscout).
(Two Scouts come on stage carrying a long pole. They prop it up, then stand back and look at it.)
Scout 1: Now, there are several ways we can figure out the height of this pole. How do you want to start?
(The Scouts unsuccessfully try various methods of estimation to calculate the height of the pole. The conversation goes something like....)
Scout 1: According to my calculations, that pole is about 2 m high.
Scout 2: There's no way. It has got to be shorter than that. Just look at it.
(This kind of exchange repeats several times as the Scouts obviously become more and more exasperated. A Cub strolls onto the stage.)
Cub: Hi! (he watches a bit) What are you guys trying to do?
Scout 2: We're trying to measure the exact height of this pole.
Scout 1: We haven't had too much luck, yet, but we'll get it.
Cub: Why don't you just lay the pole on the ground and measure its length?
Scout 1: (scornfully) Cubs!
Scout 2: I'll say. (To the Cub) Didn't you hear right? We want to know how tall the pole is - not how long it is
