April Fools!!!
Riddle: As an April Fool's joke, a prankster, who works in an assisted living facility, created a flyer and distributed one to each room of the facility. Here is what the flyer announced: Attention!!! All residents!!! Several creatures have recently been spotted in hallways and day areas of this facility. The primary creature seen is reported to be warm-blooded, is between 60 and 72 inches in length, and has three legs and three feet. There have even been rarer sightings of several of these life forms having six legs and six feet. Anyone sighting either of these two creatures should immediately notify the receptionist for instructions. What do you suppose the living organisms were to which the prankster was referring in his April Fool's flyers?
Answer: The "creatures" to which the prankster was referring, were the residents who used canes and walkers. Each cane acted as a resident's third leg, with a foot at the base of each cane. The rarer "creatures" were the residents using four-legged walkers with a foot at the bottom of each leg. These sums were added to each resident's physical two legs and two feet which accounted for the description of the "life forms" in the flyers.
