A bookie was walking the grand national course. At the water jump he sees a little girl with a rod and a float in the water. "You'll never catch anything in there" he says. Girl asks, "what odd will you give me?" Bookie, "20 to 1" Girl, "okay,here is £1" Bookie takes the money and as he is walking away the Girl shouts him back. He turns to see a flat fish on the hook. "Fair enough, here you go." And he hands over £6. Girl, "But I should get £20 plus my original £1" Bookie, "Sorry, it's quarter odd for a plaice" I'll get my coat.
