Not that it has any relevance to this story, but there is that line from the Corey Harris blues tune Fish ain't Bitin' no more":
"Give a man a fish, teach him how to fish, bring the whole school to his door, but what he gonna do when the water dry up and the fish ain't bitin' no more?"
I have a fisherman friend who has a sign in his office.
Give a man a fish and he eats for a day. Teach a man to fish and he has to buy:
Graphite Reels
Special test lines
Bobbers, weights, lures, and hooks
Charters
Boats
Waders
Bait
etc. etc.
