Another sketch that doesn't seem to have any educational value, though I've only seen it in The Sesame Street Book of Puzzlers, is one where Ernie is upside-down on the ceiling, planning on pouring a glass of milk, with Bert saying that you can't pour milk upside-down, but Ernie manages. I know that those early books didn't include word-for-word dialogue, so I'm not sure if there was any educational value missing from this sketch in the book, and I don't think anybody here has any memory of ever seeing that sketch.
