Talkin' Business

So two years ago I got a bunch of business cards and pocket calenders to help promote the blog. I think like 500 of each or something like that. I just came across them and I still have about 200 business cards and I threw the calenders away because they were for 2010. Anyways, I''m trying to figure out what to do with the rest of the business cards. In the past I left them around my dorm and the MUB and stuff.

My question to you is what should I do with the remaining 200 cards? Help me come up with an idea for some sort of scavenger hunt or something. I'm a liberal arts student, WSBE kids help me out! What do I do with business cards?
