Geordie, Charlie and Tucker go for the same job. The manager says he wants each of them to go into his office one at a time to take a test. Charlie goes in and is presented with a potato, a lettuce and a knife. The manager asks him which one is the odd one out.
Charlie says, “The knife, that’s mineral and the other two are vegetable.”
“Well done,” says the manager, “send in the next applicant.”
Tucker is presented with the same test. He says, “The knife, you can eat the other two.”
“Fair enough,” says the manager, “send in the last applicant.”
Geordie goes in and is faced with the same test. He answers, “The lettuce.”
“How have you reached that conclusion?” asks the manager.
Geordie says, “Haway, it's dead easy, ye can make chips with the other two!”
