On the appointed day, the inspector turned up.
"Tell me about your staff," he asked Paddy.
"Well," said Paddy, "there's the farm hand, I pay him £240 a week, and he has a free cottage".
Then there's the housekeeper. She gets £190 a week, along with free board and lodging.
There's also the half-wit.
He works a 16 hour day, does 90% of the work, earns about £25 a week along with a bottle of whisky and, as a special treat, occasionally gets to sleep with my wife."

"That's disgraceful" said the inspector, "I need to interview the half-wit."

"That'll be me then," said Paddy.
