I'm taking a course in food and drug law this semester, which has turned out to be a lot of fun. Reading the casebook, I came across this excerpt from a deposition. I think it speaks for itself;

Q. Mr. Konicov, does your firm still market a tape called "Astro Sounds"?

A. Yes, we do.

Q. How does it differ from the other tapes?

A. It's just a bunch of loud, squeaky noises.

Q. And what is it supposed to do?

A. I don't know.

Q. Why do you sell the tape if you don't know what it does or purports to do?

A. Why?

Q. Yes.

A. To give people a choice to buy it or not to buy it.
