An old-timer sat on the river bank, obviously awaiting a nibble, though the fishing season had not officially opened. A uniformed officer stood behind him quietly for several minutes. "You the game warden?" the old-timer inquired.

 

"Yup."

 

Unruffled, the old man began to move the fishing pole from side to side. Finally, he lifted the line out of the water. Pointing to a minnow wriggling on the end of the line, he said, "Just teaching him how to swim."
