Sally: Hey, Don, you know what we should do tonight?
Don: Yes. But what were you thinking?
Sally: We should go back to your place and watch TV. They're showing a kidney transplant on cable.
Don: Oh. Sounds like fun, but I gotta work late tonight.
Sally: Oh, but I don't get the Surgery Channel.
Don: Oh. Well, Sally, there's no reason you gotta miss it. Why don't I give you my key?
Sally: Great. I'll put it under your mat when I'm done.
Don: Say, when you're done, why don't you just hang on to it?
Sally: Really? Your key? Oh, Don, it's beautiful. Oh, look! It's a Schlage! My favorite.
