A door to door salesman knocks on a door and an old lady opens it. "Would you like to buy this hoover madam?" he asks "eh?" she replies. "This hoover is the best you can get!! It's the latest technology!!" he insists, "eh?" she says. Being the determined salesman he says "Let me demonstrate this hoovers power!! It really is fantastic!!" but all the woman can say is "eh?!"
The woman is clearly deaf, so he gives up and walks away, "shut the gate on your way out!" the woman shouts! "Oh sod you and your gate!" he mumbles! "Sod you and your hoover too!!" she replies!
