@Pile of Pooh. Cut across the fold? No he didn't. When he cut it there was no fold. And not only do the cuts not cross the fold, but the fold doesn't cross the cuts. So clearly you are not a math professor. Indeed, like Pooh, you would seem to have very little brain.

This isn't really that amazing. No offense but it reminds me of the Seinfeld episode when Elaine stops having sex and is amazed by a tire display.

I don't understand how this is a puzzle. Am I missing something?

He cut across the fold. Wow, that was hard. I are a math professor?
