    A strange thing happened in London recently. A large number of Englishmen started roaring and eating
food off the floor. They were behaving like a pack of lions. No, they weren't going bananas. They were
normal people like you and me. But they watched a "therapist" on a daytime TV show. They were convinced by
him that roaring is good for you. "Roaring helps people who are uptight to relax," he said.
    The "therapist" turned out to be a hoaxer. He goes around the world playing tricks on people. It's all
for fun. So if you don't want to feel like a fool, watch out! You can't always believe what you see, read
or hear.
