Elaine: You want to sit down?
Hal: Oh, I don't sit on park benches. They're very bad for the back.
Elaine: Really?
Hal: I threw my back out about 15 years ago. Ever since, I have been very careful. I only buy furniture in the ergonomics store.
Elaine: Oh, those places have the stupidest names. Like, uh, "Back in business", or "Good Vertebrations".
Hal: Not this one. It's called the "Lumbar Yard".
