I don't know... you can fit an awful lot on T shirts nowadays...
Monday evening a band director had a T shirt what headlined "Music Theory Much?" and had a lot of fine print which i woulda felt awkward asking if i could read, and was tempted to comment that i'd wear a shirt like that if only it was written so i could read it.
Then later at another rehearsal a trumpet player was wearing a T shirt titled "Physics Crib Shirt" for everyone else, and at closer glance, everything else was written the right way.
Yeah, a lot will fit, not even needing microfiche technologies...
