"He did for bullshit what Stonehenge did for rocks." - Cecil Adams?

Factual Questions
1

Not sure where this should go, so I’ll try here…

On another website someone used as a signature, "He did for bullshit what Stonehenge did for rocks - Cecil Adams". A little Googling produced this thread (Nostradomus) where Unca does indeed use that phrase. My question is is that the first use of that phrase? Did The Perfect Master actually come up with that on his own? I thought it was older than that.

25 years isn’t old enough?

I could have sworn it was something about cornflakes and General Mills. Anyone else remember this?

I think that CA quote was something like, “If ignorance were cornflakes, you’d be General Mills.” But that’s from memory, and I don’t remember the context, so you’re on your own, accuracy-wise…TRM (ending with another quote)

That’s it. Thanks!

“There are two schools of thought on Nostradamus: either (1) he had supernatural powers which allowed him to prophesy the future with uncanny accuracy, or (2) he did for bullshit what Stonehenge did for rocks. I incline toward the latter view.”
