Once W.S. Gilbert was at a gathering where he was greatly vexed by an exceedingly enthusiastic and unctuous admirer. The praise for Gilbert's latest operetta went on and on. When the admirer has finished with Gilbert she prepared to treat his partner, Sir Arthur Sullivan, to a similar fate.
"How wonderful," said she, "To think of dear Sir Arthur composing and composing just like Bach."
"Madam," interrupted Gilbert, "Sullivan may be composing but Bach is decomposing."
