Emma: Where can we get some more water? Ricky: There’s a pump down the road. Take the container hooked on the back of the truck with you.
Emma: This job will be a snap. I’ll show you that I’m nobody’s fool.
(Emma returns from fetching the water.): I’m back. Ricky: What were you doing on the way back? The container is half empty.
Emma: What? Hey! You sent me on a fool’s errand. This container has a hole in the bottom!
Ricky Sorry about that. I hope your shoes aren’t soaked.
Explanation: Nobody’s fool - not stupid Example: You can’t put anything over on Ryan – he’s nobody’s fool.
