In Archie Armstrong's Banquet of Jests (1641), the following passage occurs:
A Gentleman and a Parson.
Some pleasant Gentlemen riding by the High-way, espyed a Countrey Parson before them. Sayes one of them, yonder is a Scholler, let us mend our pace, and you shall heare me pose him with a question. They did so, and after a sleight salutation; Master parson, saith he, I pray you can you resolve me what part of speech is Qui mihi decipulus? Yes sir, I can, replies the Parson; Puer es, cupis atque doceri. The words are so familiar, they neede no Interpreter.
Unfortunately, the words are not so familiar to me, and need an interpreter.
