A city slicker moves to the country and decides he's going to take up farming^{1. He heads to the local co-op and tells the man, Give me 100 baby chickens. The co-op man complies2. A week later the man returns and says, Give me 200 baby chickens. The co-op man complies.
Again, a week later the man returns. This time he says, Give me 500 baby chickens. Wow! the co-op man replies, You must really be doing well!
Naw, said the man with a sigh, I'm either planting them too deep or too far apart!}
