Nearly 40 years ago I took a stats course where we proved, among other things, the Rao-Blackwell theorem. But even though I studied the proof and did the exercises I never really got it. But lying in bed awake last night I finally grokked why it's true. Sadly I have no use for this newly acquired understanding.
