Riddle: When Eric and his friends returned to school after the summer break, they each told each other how their summers went. Eric boasted about the months he spent in Chile and how hot it had been. Eric's friends called him a liar. Why?
Answer: Assuming that these friends live in the United States, if it's summer in the U.S (which is in North America), it's winter in Chile because Chile is in South America. It can't possibly be hot during the winter. Therefore, Eric lied about being in Chile.
