Anyways, due to my lack of creativity, I go to the a mind-numbing awesomeness and manpower of TL, I shall ask you for one request:
T-Shirt ideas that fit the genre of AP Calculus. It can be witty, deep, self righteous, etc.
EDIT: If you have some idea in terms of an image (i.e. IIRC, last year was "Integrals, my Antiderivitive" with the antidrug advertising campaign as a design. Secondly, I have no problem hiding a TL emblem in there somewhere, haha.
Back to the point, for the ideas, if you have an image, you can just describe it. We'll find a way to get it into print.
