Variation on youfoundthecard PENS People steal pens all the time. You put one down, it vanishes. If you're handing them out free, people will take a handful, and then other people steal them. It probably isn't that expensive to get pens made up with a url on them- something catchy like 'youstolemypen.com' and then leave them lying around. They'll pretty much distribute themselves. Good idea? Workable?
