I'm pretty smart, if I say so myself.
Why is that?
This afternoon, we walked into a fruit store, and the clerk thinks I'm some out-of-town hick. "Those apples will be two bucks each," he tells me. That's where I outsmarted him. I pass over a five. And as he's about to give me a dollar change, I say, "Keep it, we're even. On the way in, I stepped on a grape."
