Riddle: The distance from the Earth to the Sun is about 100 million miles. The speed of light is 186,000 miles per second, and light takes eight minutes to reach the Earth from the Sun. Let's say the Sun rose at 6am this morning, and that by some freak of physics the speed of light is suddenly doubled to 372,000 miles a second. What time will the Sun rise tomorrow?
Answer: 6am again. After all, what diffrence does the speed of light make to the answer?  It's irrelevant- only the speed of the roation of the Earth matters here.  
Riddle: A husband and wife are seated facing each other with a barrier between them. Each one takes turns communicating with the other, each speaking only two words at a time. After each two-word message is conveyed, the other person answers with a one-word response. This goes on for some time, until at last, either the husband or his wife suddenly shouts out a four-word phrase which ends this scenario; however, this often causes either the husband or the wife to become angry or frustrated with the person who shouted the four-word phrase. What is going on here?
Answer: The husband and wife are playing the old game of BATTLESHIP. The two-word communications consist of a letter and a number for the coordinates of where the ships are hidden, and the one-word responses are either, "Hit" or "Miss". The final four word phrase which ends the game is, "You Sank My Battleship!"
Riddle: "May Day! May Day! May Day! May Day!" shouted an angry wife to her cringing husband. "This is my official warning for you to remove that dead plant from this house before the stroke of midnight tonight!" "But it holds a lot of sweet memories from last year for me," responded her husband. His wife fired back with, "Today is the first of May, and you should have removed your precious plant from the premises months ago. Besides, it is both dead and brown and is now as sharp as a cactus, and to top it off, it has become a genuine fire hazard." Her husband sheepishly answered her by saying,” Well, I was hoping to set a Guinness world record for the family; but if I must dispose of it, the least you can do is help me remove all the shiny stuff from it first. What kind of a plant do you suppose this was which could create such a strange-sounding argument between this husband and wife?
Answer: The husband was having trouble parting with his beloved Christmas tree which was still standing in all of its tinseled glory in their living room, since it was erected in December of the previous year.

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.

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.

Riddle: Marge and Lucille were best of friends, but both of them were highly competitive. One day they entered a grueling 50-mile bicycle race along with a large group of other contestants. Lucille was the more experienced of the two riders, but throughout the race, Marge was always out in front of her. Not once did she allow Lucille to pass her, but Lucille's fiery, competitive spirit would not be quenched, as she never let Marge out of her sight for even one instant. Even after 50 long miles, Marge and Lucille were only separated by a couple of feet, with Marge finally passing the finish line less than one second ahead of Lucille. Neither racer won, but they both finished in the top ten of all the competitors. After the race, Lucille was asked about her competing with her friend Marge. All Lucille would say was, "I couldn't have passed her, even if I had wanted to. In fact, it was impossible." What led Lucille to make such a bizarre statement?"
Answer: Marge and Lucille had been participating in a tandem bicycle race (bicycles built for two people).
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 businesswoman named Coraline was at her place of work when a young man entered. "You look like a Clark to me," said Coraline in greeting him. The man responded, "You are exactly right," and he exchanged something with her and then left. A second man entered and said, "I'm really hungry, and am looking for the nearest fast-food place." "I suggest you take 5th Avenue," answered Coraline. He then exchanged something with her and left. A rather heavy-set woman then came through the door and Coraline said, "You are definitely a chunky person!" Seemingly unaffected by the comment, the woman said, "I certainly have to agree with you," and she then exchanged something with Coraline and then departed. A policewoman then entered and said in a serious voice, "I received a tip that one of the Peanuts gang was hiding in here, and I came to take her in. "She is here," replied Coraline, and she turned her over to the officer in exchange for something. Finally, a shady-looking character came slinking in, carrying a black briefcase. "Why are you here?" asked Coraline. "It's not payday again, is it?" "You got it, Sweetie!" he replied, and he exchanged something with her and then left. What in the world was going on here, and what kind of business was Coraline operating?
Answer: Coraline was the owner and operator of a candy shop. Most of her customers were repeat customers, and she was very familiar with their specific requests before they ever stated them. In order of their entry into her store, she offered them: A Clark bar, a 5th Avenue candy bar, a Chunky square, a Peppermint Patty, and a Payday bar. Each customer simply paid for their selection and left with their favorite candy.
