Fishing?

The rain was pouring down. There standing in front of a big puddle outside the pub was an old Irishman, drenched, holding a stick, with a piece of string dangling in the water.
 
A passer-by stopped and asked, "What are you doing?"
 
"Fishing" replied the old man.
 
Feeling sorry for the old man, the gent says, "Come in out of the rain and have a drink with me."
 
In the warmth of the pub, as they sip their whiskeys, the gentleman, being a bit of a smart ass, can’t resist asking, "So how many have you caught today?"
 
"You're the eighth," says the old man.
