Name a law that we don't know about that we break, either occasionally or routinely.

Do you save flower seeds from store-bought flowers (or seeds) that produce them? I'm pretty sure it's against the law.

[Miss Marple]

Nope. I am not a seed-saver. I do know, however, that if I take a cutting from a patented rose I am breaking the law.
