One Oxfordian liked to take the English names of visiting scholars, turn them into Linear B, and then back into Greek using the very loose Ventris rules, only to find that some Greek god would always come out.
But this example is more fun (courtesy of Michael C. Stokes by way of Douglas Young):
Arma uirumque cano Troiae qui primus ab oris...
a-ma wi-ru-qe ka-no to-ro-ja qi-pi-ri-mu a-po-ri
halmai wiluite kainos Tholoiai Diphilimus apolis
ἅλμαι ἰλύι τε καινῶς Θολῳᾳ Διφιλιμος ἄπολις
That is, the first line of Virgil's Aeneid (Latin) -> Linear B -> Greek. My trans: "With brine and slime, at Tholoia [place of beehive tombs], Diphilimus is made a ruined city in an inventive way."
