Slip a "mickey" = Mickey Finn?

Two part q: Many movies and sit-coms used to use the phrase “slip someone a mickey”. What is this, and does it refer to a Mickey Finn? And, even if not, what is a Mickey Finn, anyhow?

I know, this gives new meaning to “hidden mickies” (ala Disney) :wink: !

Cecil answered this one a long time ago here.

That article doesn’t have my favorite Cecil line, which appeared in the first Straight Dope book (I’m paraphasing here): You might recall our discussion of 1890’s Chicago saloon keeper Joe Hep on page XXX. 1890’s Chicago salon keepers were obviously quite a crew.
