If you don't know head over to the Fibers.com blog, there's a post I wrote about the top five Abe Lincoln t-shirts and it explains the "Did you say Abe Lincoln reference." If you're wondering why all this Fibers.com stuff; full disclosure, I totally work there and spend 30 hours of my week doing this awesome stuff and getting paid! Yeah, it's pretty much the coolest job ever.
