Found this joke on DS:
Alex and Louise call out to Harry and ask him"Can you give us a hand?" "Sure," he replies. "What's the problem?" "Well, we've started a really hard puzzle and we can't even find the edge pieces." "Look on the box," he said. "There's always a picture of what the puzzle is." "It's a big rooster," they say. Harry walks over and says, "Okay, put the corn flakes back in the box."
