Ego-stroking

I was informed, this afternoon, by a former student of mine, that a company is selling a t-shirt emblazoned with a theorem of mine (more properly, a combinatorial object used in giving a beautiful proof of a long known theorem).  This appeared in a paper ten years ago (almost to the day), and has become known by names of me and my co-author on the paper: we didn't name it after ourselves, but others have since chosen to do so.
But, my goodness, what an incredible ego-stroke, to have somebody emblazon a t-shirt with an object others have chosen to name after you!

Yours, chuffed,
