Riddle: Little William Dilly, a five-year-old kindergarten student, approached his mother after school one day and related the following story: "Today in school I saw a man-eating lion! Then I saw a man-eating tiger! Then I saw a man-eating panther!" "That’s nice," his mother replied, only half listening to him. William continued; "And then I saw a man-eating camel and a man-eating zebra, and a man-eating sheep!" This caught his mother’s attention. "Did your class go to the zoo today? I sent no permission slip; or is your wild imagination exposing itself again --- because there are no camels, zebras, or sheep that eat people," his mother replied. "Honest, mom! I really did see everything I just told you!" Indeed, young William had seen everything he had reported to his mother. How could it be possible for William to have actually seen all he claimed to see?
Answer: Little William’s kindergarten teacher was a man who enjoyed having fun with his students. At lunchtime that day, he took out a box of animal crackers, and holding up one animal at a time he would announce to the class, “You are now seeing a man eating lion, or a man eating sheep,” etc., and then proceed to eat each cracker, much to the children’s amusement. Little William was just reporting what he had seen his teacher doing and saying that day.

Riddle: Marge and Terry are both looking intently at a 4-inch X 4-inch musical symbol, but neither of them is thinking about music. Marge initiates their activity by placing a letter of the alphabet into the upper left quadrant of the symbol. Terry counters by putting a different letter of the alphabet into the lower-right section of the figure. Marge retaliates by inscribing the same letter she used the first time, into the lower-left section of the musical emblem. Terry responds by placing the same letter he just used, into the middle-left area of the image. Marge begins to smile brightly and places the same letter she has been using into the upper-right quadrant of the figure. Terry then grimaces and writes the exact same letter he has been using, placing it in the center of the symbol. Marge then gives a gleeful laugh and puts her same letter into the top-middle of the emblem. She then draws a line and shouts out three words to Terry, which make him feel a bit sad and disappointed. What are the three words Marge shouts at Terry, and exactly what has been going on here?
Answer: Marge and Terry have been playing the game of “Tic-Tac-Toe”, and these are the three words she shouts at him after beating him. The musical symbol called a Sharp, looks just like a Tic-Tac-Toe grid.

Riddle: A man took a walk in the park. While on his walk, he came across a stray dog who began growling at him and nipped at his heels. The man pulled a crooked stick from his knapsack, told the dog to, "Fetch!", and then threw the stick. The dog made a mad dash for the stick, then suddenly made a u-turn and ran back to the man ----- without the stick. The man laughed loudly. He then said to the dog, "Let's try this again." Throwing the same stick, the man again yelled, "Fetch!", and the dog took off as before, suddenly made a u-turn, and ran back to the man ----- again without having obtained the stick. The man laughed louder. This same series of events happened over, and over, and over again until the dog finally ----- bit the man on the leg. What was going on here that so infuriated the dog to cause him to bite the man?
Answer: The man had tormented the dog in the park in the past by telling the dog to fetch the crooked stick (wooden boomerang) he carried with him in his knapsack. The dog could never catch the boomerang, which always returned to the man after he threw it, thus frustrating the dog who only wanted to play. What goes around comes around, as they say, with boomerangs and in life.
Riddle: The Mills family had traveled to their vacation cabin which was next to a large, beautiful lake in the mountains. Mr. and Mrs. Mills and their three children, Brock (age 6), Cindy (age 7), and Susan (age 8) had come to the lake to relax for the weekend. They were all looking forward to taking a long, relaxing swim in the lake, and to try out the brand new boat Mr. Mills had just purchased for some family fun. As they were swimming near the middle of the lake, it dawned on Mr. Mills that their son Brock was not in the water with them. Suddenly, with no warning, the family heard motor sounds and saw their newly-purchased boat speeding directly toward them, accompanied by the maniacal laughter of their missing child, Brock. Again and again, Brock drove the boat directly at his vulnerable family, laughing insanely each time it passed near them. "I told Brock not to go near that boat unless I was with him," shouted Mr. Mills, "and now he's trying to kill us with it!" However, Mrs. Mills nonchalantly responded, "Oh, boys will be boys." Considering the circumstances, why was Mrs. Mills so cavalier concerning her son's disobedient and reckless behavior, and why did she seem unconcerned about her six-year-old driving a boat without supervision?
Answer: Mr. Mills had bought the family a new remote controlled boat, but bad boy Brock decided to ignore his father’s instructions, and sent the two-foot long boat on its maiden voyage as a mischievous prank on his family. I don’t envy Brock when his father reaches shore.
Riddle: Inspector Bradstreet, a highly respected police detective with 25 years of investigative experience on the force, was in a room with four homicide suspects: Joan, Shirley, Dorothy, and Irene. He was in the room with the four of them for at least 15 minutes, but for some reason, he had not started interrogating the suspects, despite the fact that a dead body, which had a knife sticking out of its back, lay on the floor in the room with them. One of the four suspects had called 911 to summon the police at some point. Why hadn't this highly decorated and respected detective started his investigation into the obvious murder by questioning the four suspects? For what reason was he waiting?
Answer: Inspector Bradstreet was dead. It was his body that had the knife stuck in it.
