Paddy McCoy, a weather-beaten Irish farmer, received a letter from the Department for Employment & Pensions stating that they suspected he was not paying his employees the statutory minimum wage and they would be sending out an Inspector to interview them all and to check Paddy's wages books.
On the appointed day, the Department Inspector turned up. "Tell me about all your employees," he demanded.
"Well," said Paddy, "there's the farm hand. I pay him £240 a week, and he has a free cottage for him and his family.
"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 me missus."
"That's disgraceful!" exclaimed the Inspector, "I want to interview the half-wit."
"That'll be me then," replied Paddy.
