I don't get the four-sprung duck call one.The "Silly rabbi" is a spoof on a line from a breakfast cereal commercial: "Silly Rabbit, Trix are for Kids" (the rabbit in these commercials is always trying to steal Trix(TM) brand cereal, but it's just for kids, don't you know.)
And now, from the punny headlines department:
All toilets at precint stolen overnight. Police have nothing to go on.
