return to (one's) muttons
antiquated To return to a given topic or subject that one is discussing, explaining, ruminating over, talking about, etc. Taken from a humorous translation of the French idiom "revenons à nos moutons" (literally, "let us return to our sheep," which has the same meaning), which itself came from the medieval play La Farce de Ma?tre Pathelin. The constable, frustrated with the drunkard's rambling explanation, bade him return to his muttons. But I have strayed off course from the lecture, so let us return to our muttons before we run out of time.
laced mutton
An outdated term for a prostitute. A: "I think that Lord Stewart is spending time with a laced mutton." B: "No, surely not!"
