yah, he's a fellow here. the table on the back of the shirt is one of Dr Hendrickson's complex "phenospace" lectures pertaining to one of the key uterine SM papers by him. He loves the stats, and that fellow had been asking around about shirt design etc but went ahead and made a prelim one himself based on his fascination with that phenospace concept. Agreed though, we did appropriately teased him about when he showed us, although to my knowledge he hasn't been caught wearing it.
