The new Jim Butcher store there also has a Bob quote: "Harry, What you know about women I could juggle." The 'Splattercon' merch from Proven Guilty.
And a couple others...
I went with the black v-neck tee with yellow lettering. (on the quote mentioned above)
Oh... And also... the fact that they now offer womens thongs with Bob the skull on them must make that particular air spirit VERY happy.
