A city slicker moves to the country and decides he's going to take up farming. He heads to the local co-op and tells the man, "Give me 100 baby chickens." The co-op man complies. 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!"
