Why is this night exactly the same as last night?
Last night, we had a seder. Tonight, we're having exactly the same seder.
Last night, I asked you four questions. Tonight, I'm going to ask you the same four questions all over again.
Last night, you made a big deal out of the Torah verse "on that day". Now, you'll do that today too?
Last night you told me the story of the coming out of Exodus. Good yarn. But you're repeating it. Didn't we cover this already?
(Chag kasher v'sameach to those celebrating this week.)
