Opt-in: Do you want me to punch you?

Opt-out: I am going to punch you, but if you don’t want me to, go to iwillpunchyou.net, navigate to the bottom of the page, click the link, download the pdf, fill it in, send it to a PO Box in Antarctica, and I’ll get back to you in six to eight years. Oh and until I take a look at it, I’m going to punch you repeatedly.
