The humor is mostly dialogue driven:

--> '''Jackie:''' Were you poor? Did you eat chicken pot pie?
--> '''Leslie:''' ''[sadly]'' Pancakes... Lots of pancakes. ''[walks away]''

--> '''Anthony:''' Would you like a glass of Liebfraumilch?
--> '''Leaslie:''' No thank you. I'll just have a glass of wine.
--> '''Marty:''' That's the name of the wine.
--> '''Leslie:''' Oh, I don't speak French.
--> '''Jackie:''' Who does?
--> '''Anthony:''' You do.
--> '''Jackie:''' Oh, that's right. I do.
--> '''Leslie:''' What does it mean?
--> '''Jackie:''' In French? I think it means something German.
--> '''Marty:''' It means 'Loving Mother's Milk'.
--> '''Leslie:''' You speak French?
--> '''Marty:''' ''[blank stare]'' No,... German.

--> '''Jackie:''' ''(after Leslie demonstrates that she can say "I Love You" in sign language)'' Don't leave this girl alone with any handsome, deaf, mutes, Marty, that's my advice to you.

--> '''Marty:''' Are you being wise?
--> '''Jackie:''' One day I woke up wise.
--> '''Marty:''' One day I woke up stupid.
--> '''Jackie:''' What'd you do?
--> '''Marty:''' I went back to bed.
--> '''Jackie:''' That was wise.

--> '''Jackie:''' Are you saving yourself for marriage?
--> '''Leslie:''' Oh, no. ''[gasps]'' Do you think I should've?
--> '''Jackie:''' If I were getting married I'd wanna check out the goods!
--> '''Leslie:''' Me too!
--> '''Jackie:''' So how are they?
--> '''Leslie:''' What?
--> '''Jackie:''' The goods.
--> '''Leslie:''' I can't talk about that. He's your brother.
--> '''Jackie:''' Pretend he's not my brother. I do.

--> '''Anthony:''' You never go hungry in the desert because of the sand which is there.

-->'''Lesly:''' I don't think you're insane.
-->'''Jackie-O:''' You don't?
-->'''Lesly:''' No.
-->'''Jackie-O:''' You don't think I'm an eensie weensie bit insane?
-->'''Lesly:''' I don't think you're insane. I think you're just spoiled.
-->'''Jackie-O:''' [exasperated] Oh please, if everyone around here is going to start telling the truth, I'm going to bed.
