[staring at Ernie's triggered-but-empty mousetrap]

I don't believe it. He snapped the trap, ate the olive, and left the pit just to mock us!

I think you're giving him a little too much credit. Mice don't mock. They don't have a sense of humor or irony. He's not sitting in his hole in a smoking jacket sipping cognac, and giggling to himself, "I left the pit!" The trap snapped itself, the olive flew off and he ate it. [He starts pouring the cereal he had gotten] It's just that simple. But now that he knows we're here, he won't come within a mile of us. I don't think we'll be seeing any more of that... [the mouse suddenly falls out of the cereal box] Mouse!
