The Downside of T-Shirts

Don't get me wrong. I love to get free stuff, especially from my company. Unfortunately, whenever we give away a t-shirt, everyone gets one and then they all wear them to work. So, if I don't want to look like one of the moron triplets, I either have to never wear my freebie shirt or find another tech worker and trade them for a shirt from their company (because presumably they've got the same problem). Maybe someone should write a website to coordinate this--SwagSwap?
