A fisherman from the city was out fishing on a lake in a small
boat.

He noticed another man in a small boat open his tackle box and
take out a mirror.

Being curious the man rowed over and asked, "What is
the mirror for?"

"That's my secret way to catch fish," said the other man. "Shine the mirror on the top of the water. The fish notice the
spot of sun on the water above and they swim to the surface. Then I just
reach down and net them and pull them into the boat."

"Wow! Does that really work?"

"You bet it does."

"Would you be interested in selling that mirror? I'll give you
$30 for it."

"Well, okay."

After the money was transferred, the city fisherman asked, "By
the way, how many have you caught this week?"

"You're the sixth," he said.
