Jess's black eye and his story about attacked by a swan. Luke doesn't believe him but humors him when they row out to the lake and try to attack the swan with a ladle.
"I'm telling you, [the swan] is vicious." "Yeah, his butt's terrifying."
At the Bracebridge dinner, Dean comments to Rory that he think Jess is a jerk. They turn to see Jess standing in the foyer talking to Luke and Lorelai and when the three of them make eye contact, Jess simply waves hello at them with a semi-innocent look on his face, making Dean seethe with irritation.
Jackson as the Bracebridge squire.
The short movie Kirk made.
Emily tries explaining her wedding day woes to Lorelai.
The minstrel at Liz and TJ's wedding. It's a funny moment in-universe as well, Luke and Lorelai are clearly trying to think of ways not to laugh while Jess makes faces in an attempt to not crack.
Before that, Liz and her friends meet up at Luke's diner. A postal worker comes into the diner with a package for Liz. Jess, being completely aware of what's about to happen, hightails it out of there and gives a clueless Luke a "Have fun!!" look. Luke has no idea ("but there's no address on it!")...until the postal worker reveals that he's really a stripper and starts dancing for Liz.
Lorelai finding out that Rory was the cause of the fight at a Wild Teen Party. She starts singing "The Wind Beneath My Wings".
In "That Damn Donna Reed", Rory dresses up as, and acts like, a stereotypical housewife as a way of teaching Dean a lesson (she thinks he was acting a little sexist). When Lorelai sees her in that outfit, she's highly amused:
Lorelai: Well, OK, you're 16. You have a whole house to yourself for the evening. I expect that you're going to have your boyfriend over. But what is with the apron?
Rory: It's a long story.
Lorelai: Did it involve a sharp blow to the head?
Rory: I gotta go check on Apricot.
Lorelai: Oh my God! I just saw the pearls.
Rory: I'm going in now.
Lorelai: You know what? I'm going inside too. 'Cause I have to write down all the ways I'm gonna torture you about that outfit.
Rory: Good night!
Lorelai: Could I just get a picture though? 'Cause visual aids would really help. Oh, oh! Oh the shoes! I am dying. Oh.
The shocked look on Lorelai's face when Floyd Stiles reveals that he knows she and Jason are dating
Kirk getting a cat and having new and worse-looking scratches every time he meets up with Lorelai, explaining how the cat (which he also named Kirk) will attack him if he doesn't "announce his presence before entering a room." Later he explains filling his tub with water and hiding underwater to hide from Cat Kirk but "he still found me", and by the end of the episode he's sleeping outside on a park bench.
