Riddle: When summer break ended, Mila told her friends about her vacation in Africa. Mila said, "Oh, it was great! But on the last day of my trip, a massive volcanic eruption happened; it didn't spoil my vacation only because I flew home that day,". Mila's friends didn't believe her. Why?
Answer: All flights must get canceled when a volcanic eruption occurs, so Mila couldn't have flown home on the last day of her vacation; she's lying.
Riddle: One afternoon, Cara came home and found that her favorite vase had been shattered. The woman questioned her three kids—Ali, Gia, and Joe. Ali said, "It was Gia!". Gia kept silent, and so did Joe. Assuming that the culprit tells the truth, who shattered Cara's vase?
Answer: It was Joe. If Ali is telling the truth, then he's the culprit. But that would make Gia the culprit, too, which would then create a paradox. Therefore, Ali is lying, and Joe is the culprit by default.
Riddle: The owner of a Lost-and-Found faced a big argument between a man and a blind woman. The two of them were arguing over car keys that they came across simultaneously. The owner decided to tell the two of them to stop arguing because he knew who the car keys belonged to. Who?
Answer: The car keys belong to the man. Remember that the woman is blind? Well, you can't drive safely if you're blind!
Riddle: Mr. Green, Mr. Brown, and Mr. Black meet up for coffee one Monday morning. Mr. Green says, "Hey, do you realize that we're all wearing shirts of colors that don't match our names?". The man wearing the brown shirt says, "Wow, Mr. Green, you're right"! What colored shirt is each man wearing?
Answer: Mr. Green cannot be wearing the green shirt, because his statement that all three men are wearing shirts that don't match their names is correct. And he cannot be wearing the brown shirt, because the man wearing the brown shirt replied to his words, and let's be honest–it doesn't make sense to reply to your OWN words, right? This means Mr. Green can only be wearing the black shirt. Mr. Brown can either be wearing a green or a black shirt. The black shirt is already taken, so Mr. Brown is wearing the green shirt. And Mr. Black is wearing the brown shirt.
Riddle: Fiona's mother has 12 children. One day, the mother comes home and sees that all 12 children are busy. The first child, January, is reading a book. The second child, February, is cooking dinner. The third child, March, is playing chess. The fourth child, April, is tidying up her room. The fifth child, May, is taking a nap. The sixth child, June, is taking a shower. The seventh child, July, is gardening outside. The eighth child, August, is lighting the fireplace. The ninth child, September, is painting a picture. The 10th child, October, is doing yoga. The 11th child, November, is doing her homework. What is the name of the 12th child, and what is he/she doing?
Answer: The name of the 12th child is Fiona, and she is playing chess with March. Fiona is the name of the 12th child because this is FIONA'S mother. And Fiona is playing chess with March because most of the aforementioned activities require only one person to do, except for playing chess; that activity requires two players.
Riddle: Jasmine was the worst student in her class. One day, her instructor, Mr. Collins, gave her a chance to stay in her class and not be expelled. He said, "Give me a statement. If the statement is true, you will not be expelled from the class. And if the statement is false, you will be expelled from the class. So, what do you say?". What should Jasmine say to stay in her class?
Answer: Jasmine should say, "I will be expelled from the class,". If we suppose that the statement is true, then Jasmine would not be expelled from the class. But then, it makes the statement false. And if we suppose that the statement is false, then Jasmine would be expelled from the class. But then, it makes the statement true. This phrase creates a paradox, as it cannot be true AND false at the same time.
Riddle: Steve woke up after a good night's sleep. He wanted to make a big breakfast for himself. He has a dozen eggs in a carton. He breaks two eggs, fries two, and eats two. How many eggs are there in the carton afterward?
Answer: Afterwards, there are 10 eggs in the carton. Steve broke, fried, and ate the same two eggs. This is because: 1) cooking the egg while it is still in its shell would be considered boiling the egg, not frying it; after all, you would need to break the egg into a pan before frying it, and; 2) you cannot eat a raw egg while it is still in the shell because of the risk of foodborne illnesses.
