These limericks take advantage of especially odd mismatches between spelling and pronunciation, usually involving family names like St. John “SIN-jǝn” and Menzies “MING-eez” (not the only pronunciation, but the one used here). A sample:
There was a young fellow named Cholmondeley,
Whose bride was so mellow and colmondeley
That the best man, Colquhoun,
An inane young bolqufoun,
Could only stand still and stare dolmondeley.
I should note that the one beginning “At the art of love…” cannot be deciphered until you reach the last line. Thanks, Trevor!
