Kermit and Grover ladder sketch --- alternate take?!?

[JLG]

Hey! So as some of us already know, for some odd reason there were two different takes of the "Golden An" sketch that were both in active circulation. One seems to have aired far more often than the other, but still. Odd as that is, I just stumbled on another one.
I was watching #1460 and it contains an alternate take of the 1971 sketch with Kermit and Grover demonstrating "long" and "short" with ladders. I see that Muppet Wiki already spotted this, having labeled the segment "alternate take."
I wonder how many other instances of this there were. It's a very odd thing to have done. Are there any other known examples besides these two?

I mean, it was pretty common for a lot of skits to have double takes.

Was it? What were some others?

Ernie tries to make Bert warm, Farley trying on hats, Sinister Sam and his itchy trigger finger, Harvey Kneeslapper and the bucket of confetti, etc.
