Here's my version of the scene where Didi thinks that Stu read the motzah thing twice.
Didi: Stu, now you've made my mother cry!
Stu: (takes off his yamacha) That's it! I can't take it anymore! Deed, could I have a word with you in private?
Didi: Sure, I guess. (they go to the back of the room)
Stu: Yes, Stu?
Stu: Didi? (suddenly shouting) YOU RUINED MY WHOLE DAY! YOU KNOW WHAT I'VE COULD'VE BEEN DOING! I'VE COULD'VE BEEN WORKING ON MY LATEST INVENTION, I COULD'VE HANGED OUT WITH POP! I COULD'VE GONE TO THE LIBRARY! I COULD'VE STAYED HOME AND PLAYED WITH MY SON! AND YET YOU ASK ME TO BE A SEDER LEADER?! MINKA'S LYING! SHE'S LYING! LYING, I TELL YOU! (pants in frustration)
Didi: Okay, okay, Stu. Calm down. Don't get excited. I'm sorry, it's just that they're aren't any other Jewish people around to do our Seder. My father's the only one. And what do you mean by my mother's lying?
Stu: You remember her saying that your father ran away earlier?
Didi: Well, yes?
Stu: Well, I don't think that's true! Boris is in this house somewhere, he planned this I just know it! I'm gonna go confront Minka and ask her where he is!
Didi: You can't! Not in that condition she's having!
Stu: Just watch me! (goes over to Minka) Excuse me, Minka, but I think you're lying about Boris!
Minka: I was lying? Vey! That's ridiculious!
Stu: Did you actually see your husband leave the house?
Minka: Well, no.
Stu: Good, then that proves you were lying! Now, if you were Boris where would you go?
Minka: I'd go up to the attic to get my favorite vine glasses?
Stu: The attic, of course! Come on, Deed.
Well, what do you think?
