Morning conversation

Linc, proffering a tiny item: What's this?
Bill: Looks like a little piece of plastic, maybe a broken Lego. Where did you find it?
Linc: Downstairs.
Bill: Where downstairs?
Linc, thinking a moment: By the cat.
(we crack up)
Bill: And where was the cat?
Linc, getting exasperated with us now: In front of the plastic!
