A blonde calls her boyfriend on the phone with a problem. "What's the matter?" he asks. "Well, I've bought this jigsaw puzzle, but it's too hard. None of the pieces fit together and I can't find any edges." "What's the picture of?" he asks. "It's of a big rooster," she replies. "All right," he says, "I'll come over and have a look." When he arrives, she thanks him for coming over and leads him over to the kitchen table where she has it laid out. He takes one look at what she's been struggling with and says, "Oh, for Pete's sake, put the cornflakes back in the box!"
