Imagine you're a famous actor working on a movie and there's a scene where you need to jump off a cliff and run through a field full of grenades. Your agent thinks it's too risky. That's when you call in the stunt double. They take over when things get too dangerous. This actor looks like he wants a stunt double now!

Animals have stunt doubles, too. Wishbone, the little dog with the big imagination, had a stunt double because he hated to swim.
