I have heard of this and have had it verified by a couple of sources, notably from one of Mike Tress’s granddaughters.
The Satmar Rebbe, Reb Yoel Tietelbaum, treated Mike Tress with a great deal of Kovod (respect). One of his chassidim was surprised at this and asked the Rebbe how he could do this? Mike was just a clean shaven guy! The rebbe replied in Yiddish (but I will write his reply in English). “In the World to Come when Mike Tress gets there they will ask him, “Yid, Yid where is your beard? When you get there, they will ask beard, beard, where is your Yid!”
