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: Your grandma baked three cupcakes for you, and she's letting you eat one of them. She knows that you don't like strawberries, so she lines the cupcakes in a row and tells you, "The orange cupcake is not in the middle. And the apple cupcake is not next to the orange cupcake,". Which cupcake is strawberry-flavored?
Answer: The orange cupcake is not in the middle, and the apple cupcake can't be in the middle either because it would contradict your grandma's second statement. Therefore, the orange and apple cupcakes are on the ends, and the strawberry cupcake is in the middle.

The security officer then asked the supposed geographer, "Have you ever been to the capital of Spain, that is, Granada?". The geographer said, "Yes! It's a beautiful city!". Who was the smuggler?
