Per Rule Six I think you may need to rephrase your question to find something else in the same strip to ask a question about, and then have Roy's tee-shirt be a "fun little bonus".
Of course, I'm not in charge of moderating this thread (or any other thread), so feel free to ignore me if you think I'm off base! (Always be polite wihen talking to mods - moderators, not modrons, although you should probably be polite to them, too.)
