Junk mail

Everyday I go to the mail box and I have more junk mail than I have bills, which is ok I guess. Anyway, I have a great idea and someone probably already thought of this. Open your junk mail and pull out all the crap they gave you. You know that nice little self addressed prepaid envelope they gave you to reply? Fill it back up with all the shit they sent you and send it back to them. I wonder how long it will take for them to stop sending us this crap. Just a thought for the day.
