toyota multi-billion brown coal, page-119

I have just posted this else where and find it's meaning relevant over here, plus being a cattle farmer, I like the joke.

There were two bulls standing at the top of a hill, one old, one young. Down in the valley was a herd of cows.
The young bull turns to the old bull and says " let's run down there and have us some of those cows."
The old bull replies " easy young fella, let's walk down and have them all."

A bit like many pennies, patience will reap the rewards.
