Riddle: Spencer wakes up in the middle of a forest. A few seconds later, a witch and three magic tunnels–a red, a yellow, and a blue–appear in front of the guy. The witch tells Spencer, "Two of these tunnels will make you disappear forever, and the other one will send you back to your house. Listen to these clues VERY carefully,". Clue 1: Choose the red tunnel, and you won't not disappear. Clue 2: It's a lie to say that the yellow tunnel isn't dissimilar. Clue 3: The blue tunnel doesn't have less in common with the red than with the yellow. Which tunnel should Spencer choose?
Answer: Spencer should choose the yellow tunnel. If he chooses the red tunnel, he will not NOT disappear; in other words, Spencer WILL disappear if he enters the red tunnel. We can therefore exclude the red tunnel. If he chooses the blue tunnel, he will also disappear; this is because the blue tunnel doesn't have less in common with red than yellow. In other words, the blue tunnel has more in common with red than yellow, so the blue tunnel will also make Spencer disappear. Choosing the yellow tunnel is the safest option because if it's a lie to say that yellow isn't dissimilar, the truth is that yellow IS different from the red and blue tunnels.
Riddle: Mrs. Harris went to the police station to file a report. She said that someone had attacked her. Here is her story: "I was in the restaurant bathroom, fixing my makeup. Suddenly, a stranger hit me on the head! I didn't see what this person looked like because he approached me from behind!". The police officer refused to file the report and sent Mrs. Harris home. Why?
Answer: If Mrs. Harris was fixing her makeup, she was most likely looking in the mirror (after all, she wouldn't want to ruin her makeup, right?). If someone had approached the woman from behind, she would have DEFINITELY seen what he or she looked like. Therefore, Mrs. Harris lied, and made up the whole story.
Riddle: Leslie bought some ice cream on Friday. She kept all of the flavors a secret from her friends, although she wanted to enjoy it for dessert the next day. When Leslie woke up on Saturday, she didn't find the ice cream; someone had eaten it! The girl decided to ask her friends if they had eaten the ice cream. Geoff said that he was about to leave for work, and hadn't seen anything. Christian said that he was excited to try the new butterscotch ice cream on Saturday, albeit afraid that he was going to miss it. And Margot said that she didn't even know about the ice cream, but was also willing to try it. Who knows something?
Answer: Christian couldn't be sure that there was a butterscotch taste among the ice cream flavors because Leslie kept all of the flavors in secret. Therefore, he knows something about the stolen ice cream.
Riddle: There are 10 people standing near a large swimming pool. Three of them think about jumping into the pool. How many people are standing by the pool now?
Answer: 10. Those three people simply "thought about jumping into the pool"; they didn't actually jump in.
Riddle: A bus driver goes the wrong way on a one-way street. He passes two stop signs without stopping, and he even ignores all of the traffic signs. The driver passes the cops, but they don't arrest him. Why?
Answer: Nowhere in this riddle did I say that the bus driver was actually driving a bus; after all, he was walking!
Riddle: Charlotte is a runaway criminal. She needs to get a haircut so that the police officers do not recognize her right away. There are only two hairdressers in her town, however; the first salon is run by Thomas–he has a super messy haircut and his shop is super dirty. And the second salon is run by Debbie–she has a super neat haircut and her shop is super clean. Which hairdresser should Charlotte choose for a nice haircut?
Answer: Charlotte should choose Thomas. Since there are only two hairdressers in her town, they can't cut their own hair; they gave haircuts to each other (Thomas cuts Debbie's hair, and Debbie cuts Thomas' hair). Since Thomas must have been the one to give Debbie a neat haircut, and Debbie must have been the one to give Thomas a messy haircut, Thomas is much more professional, and Charlotte should get her hair done by him.
Riddle: Four friends went out one night. During the trip back, they tried to squeeze under an umbrella, but it was too small for them to fit through. Still, everyone managed to stay dry by the time they arrived home. How can this be?
Answer: It wasn't raining. I didn't say that it was raining after all!
Riddle: Ty has four frogs-Lily, Hoppy, Croaky, and Icky–and he needs you to identify their colors. One of the frogs is black and blue, while the other three and black and orange. Assuming that both of the following statements are true, can you guess which frog is black and blue? 1) Lily and Hoppy are of the same color. 2) Croaky isn't black and blue.
Answer: Icky is black and blue. If Lily and Hoppy are of the same color, then both of them must be black and orange because only ONE of the frogs is black and blue. And if Croaky isn't black and blue, then he is black and orange. Therefore, Icky is the only black and blue frog among the four frogs.
Riddle: Betty and Becky are twins, who love to lie on certain days. Betty lies on Mondays, Tuesdays, and Wednesdays, while Becky lies on Thursdays, Fridays, and Saturdays. One day, you come up to the twins and ask them what day it is. They say, "Yesterday was one of my lying days," in unison. What day is it?
Answer: It can't be Sunday because both girls would be telling the truth…and someone is obviously lying now. It can either be Monday or Thursday because on those days, either Betty or Becky lies. But if it's Monday, both girls would lie saying yesterday was a lying day. Therefore, it's Thursday; Betty is telling the truth, and Becky is lying.
