Summer sale on Teach the Controversy shirts

We've purchased a few of these designs, at 25% off... I didn't get them in time for TAM6, but I wore the element one this weekend. Kat and I each have one of the "because we know that dinosaur bones were really planted by beelzebub" shirts, and I've got the "because we know that the earth sits on giant elephants which in turn ride on an even gianter turtle" one along with the "because we know that the real periodic table of elements only numbers five" shirt.
