Among my favorite phrases of American English is:
which is excellent all by itself, and the elaborated form
which is maybe a little overdone, but I admire its inventiveness. Who thought this up? It's genius. So specific, so evocative! It really calls to mind a picture of this person struggling to figure out how to pour piss out of a boot, which is fucking hilarious.
Poking around a bit in Google Books, the earliest citation I can find

I think it's interesting that both of these early citations are about how someone ain't got sense to…. I wonder if they're both alluding to some earlier instance, maybe prominent at the time, that was phrased that way.
Watkin is better-known for writing the screenplay for Walt Disney's 1950 film version of Treasure Island.
