 What can I do for you, Mrs. Hornbeck? I'd like some aspirin, please. Aspirin? Any particular brand? Well, which is best? Well, they're all minoacetic acid ester or salicylic acid. They're all what? They're all aspirin. Pee-bee, the tickets. Keep your shirt on. You mean there's no difference between any of them? Well, I wouldn't say that.
