Reminds me of the time an aquaintance went to lunch with me and a
few of the other engineers. He was in a rather "know it all"
mood. I started plying him with questions about how water
softeners work, what causes gravity, etc. He was doing good
until I asked him, "Ever wake up on a wednesday and think it was
tuesday all day and then wake up the next day and everything is
ok again? What is that called?" He shut up after that.

Groundhog day?
