The Catch

A kind-hearted fellow was walking through Central Park in New York and was astonished to see an old man, fishing rod in hand, fishing over a beautiful bed of red roses. Feeling bad over the old man’s clearly deteriorating mental abilities, he stopped by to see if he could help.
“What are you doing, my friend?” he asked the old man.
“Fishin’, sir.”
“Fishin’, eh. Well how would you like to come have a drink with me?”
The old man stood put his rod away and followed the kind stranger to the corner bar. He ordered a large glass of vodka and a fine cigar.
His host, the kind fellow, felt good about helping the old man, and he asked, “Tell me, old friend, how many did you catch today?”
The old fellow took a long drag on the cigar, blew a careful smoke ring and replied, “You are the sixth today, sir!”
