Irish Fishing

It was raining hard and a big puddle had formed in front of an Irish pub.
An old man stood beside the puddle holding a stick with a string on the
end and jiggled it up and down in the water.

A curious gentleman asked what he was doing.

'Fishing,' replied the old man.

'Poor old fool' thought the gentleman, so he invited the old man to have a
drink in the pub.

Feeling he should start some conversation while they were sipping their
whiskey, the gentleman asked, And how many have you caught?'

'You're the eighth.'
