Two Men Wrote a Lexicon

Edward Waterfield, in The Oxford Dictionary of Quotations, new ed. (Oxford: Oxford University Press, 1999; rpt. 2001), p. 804:

Two men wrote a lexicon, Liddell and Scott;
Some parts were clever, but some parts were not.
Hear, all ye learned, and read me this riddle,
How the wrong part wrote Scott, and the right part wrote Liddell.

Many variations are printed in The Periodical, Volume VIII, No. CX (April 15, 1921) 40-41.

Greek Comedy, Hellenistic Literature, Greek Religion, and Miscellanea: The Academic Papers of Sir Hugh Lloyd-Jones (Oxford: Clarendon Press, 1990), p. 235:

When boys at Westminster School used to defend eccentric interpretations criticized by their Head Master, H.G. Liddell, by saying they had found them in the lexicon of which he was an editor, Liddell used to say, 'Scott wrote that part.'
