(Non-majors: in the “Cyclops” episode of Ulysses, the men in the bar pass around a letter from a hangman offering his services to the High Sheriff of Dublin. The letter ends, “i have a special nack of putting the noose once in he can’t get out hoping to be favoured i remain, honoured sir, my terms is five ginnees.” Then, with the capital letters firmly in place, comes the signature: “H. Rumbold, Master Barber.”

(In the “Sirens” episode a pretty part of the decor is “Bronze by gold, miss Douce’s head by miss Kennedy’s head” — that is, in a different bar, the heads of two flirtatious barmaids, redheaded Miss Douce and blonde Miss Kennedy.

(And one more joke, about the real H. Rumbold, is spelled out for the historical record in the preface to Tom Stoppard’s Travesties.)
