One of the references of the paper
Paulo Régis C. Ruffino, A Criticism on "A Mathematician's Apology" by G. H. Hardy (arXiv:1112.4499 [math.HO])
is:
Vershik, A. M. – A Dangerous Joke, The Mathematical Intelligencer, Vol.20 no 2 1989
But neither the (online) contents page of the Intelligencer, nor Vershik's homepage seems to know this latter paper, and even Google doesn't seem to know about it. (BTW, Vol 20 of the Intelligencer dates from 1998, not 1989, but I checked both places.)
Does anyone know this paper?
