Dr Johnson said that a pun was Shakespeare’s fatal Cleopatra. I want to argue that puns are, appropriately enough, at work with particular vigour in a play about one of Cleopatra’s lovers. Julius Caesar features a series of puns very early on, starting with the Cobbler’s ‘[a] trade, sir, that I hope I may use with a safe conscience, which is indeed, sir, a mender of bad soles’ (1.1.13–14),2 and followed by his retort to Flavius – ‘[n]ay I beseech you, sir, be not out with me: yet if you be out, sir, I can mend you’ (1.1.16–17) – and finally by ‘[t]ruly, sir, all that I live by, is with the awl’ (1.1.22).
