Riddle: At a local bar, three friends, Mr. Green, Mr. Red, and Mr. Blue, were having a drink. One man was wearing a red suit; one a green suit; and the other a blue suit. "Have you noticed," said the man in the blue suit, "that although our suits have colors corresponding to our names, not one of us is wearing a suit that matches our names?" Mr. Red looked at the other two and said, "You're absolutely correct." What color suit is each man wearing?
Answer: Since none of the men are wearing the color of suit that corresponds to their names, and Mr. Red was replying to the man in the blue suit, it had to be Mr. Green to whom he replied. We then know that Mr. Green is wearing a blue suit. Therefore, Mr. Red is wearing a green suit and Mr. Blue is wearing a red suit.
Riddle: I make hair stand on end, whisper between radio stations, and yet I refuse to change. What am I?
Answer: Static. Static electricity makes hair stand on end. “Whisper between radio stations” points to the hissing noise called radio static. “Refuse to change” uses the other meaning of static: something fixed or unchanging. The riddle hinges on the word “static” having both electrical and descriptive senses.
Riddle: I am round, I am sharp, I am small, I am big, I exist, then I don't. What am I?
Answer: The Moon. It's round when it's full, it's sharp when it's a crescent, its size can vary depending upon its phase, and it's gone when it's a new moon.
Riddle: I'm not the alphabet, but I have letters. I'm not a pole, but I have a flag. What am I?
Answer: A Mailbox. A “mailbox” has “letters,” but they’re mail, not alphabet characters. It also has a “flag,” the small lever you raise to signal outgoing mail, even though it isn’t a pole with a flag. So both clues fit a mailbox through wordplay.
Riddle: It keeps something that cannot be kept, And wakes you when you have slept. It may go slow or stop at times, But even then it chimes.  What is it?
Answer: An alarm clock. “It keeps something that cannot be kept”: Time can’t be held; a clock only measures it as it slips by. “And wakes you when you have slept”: The alarm rings to wake you. “It may go slow or stop at times”: Clocks can run slow or stop (dead battery, mechanical hiccup). “But even then it chimes”: Many clocks still chime or ring on the hour/alarm, even if their timekeeping isn’t perfect. 
Riddle: I hold countless voices that never speak, countless journeys that never move, and ask for quiet to share them all. What am I?
Answer: Library. "I hold countless voices that never speak": This refers to the vast number of books in a library. Each book contains the "voice" (ideas, stories, knowledge) of its author, but the physical book itself is silent. "countless journeys that never move": Books describe "journeys" (adventures, travelogues, fictional quests), but the books remain stationary on the shelves. The reader takes the journey through their imagination. "and ask for quiet to share them all": Libraries traditionally require a quiet atmosphere so that patrons can read, study, and focus on the material within the books without distraction.
Riddle: What is it you have to answer? But to answer you have to ask? And to ask you have to speak? And to speak you have to know, The answer.
Answer: A riddle.
Riddle: Which letter of the alphabet has the most water?
