- The extras on the special edition DVD say that the late, great Rodney Dangerfield was this for the rest of the cast. Chevy Chase tells the story how, during the first day of filming, Rodney was getting progressively more concerned that he should quit the part and let someone else do it because he was doing such a terrible job. When Chevy asked why he thought he was doing a bad job, Rodney said it was because nobody was laughing. This was his first film and his entire career had been in front of audiences, doing standup; Rodney noticed that not only the crew wasn't laughing, but they were all acting very stiff and strange during his parts and it made him very uncomfortable. Chevy had to explain to him that the reason was because every member one of the cast and crew felt he was by far the funniest guy on the set and everyone was doing everything they could just so they wouldn't laugh and ruin the shot.
- The ridiculous amount of kids in the house at the beginning. The number just keep getting larger as the scene progresses!
- Carl's story about being a "looper for the Dalai Lama".
Carl: So, I tell them I'm a pro jock, and who do you think they give me? The Dalai Lama, himself. Twelfth son of the Lama. The flowing robes, the grace, bald... striking. So, I'm on the first tee with him. I give him the driver. He hauls off and whacks one - big hitter, the Lama - long, into a ten-thousand foot crevasse, right at the base of this glacier. Do you know what the Lama says? "Gunga galunga... gunga, gunga-lagunga". So we finish the eighteenth and he's gonna stiff me. And I say, "Hey, Lama, hey, how about a little something, you know, for the effort, you know." And he says, "Oh, uh, there won't be any money, but when you die, on your deathbed, you will receive total consciousness." So I got that going for me, which is nice...
- The funny moments start around 5 minutes after the film starts and go on until the credits finish rolling, but their high points are whenever Rodney Dangerfield — or his "I'm in the Money" honking car — takes the stage.
- Al: "This is the worst-looking hat I ever saw! You buy a hat like this, I'll bet you get a free bowl of soup. (he turns and sees Judge Smails wearing the hat) Oh, it looks good on you though." (Smails discards hat and storms off)
- "HEY, SMELLS!"
- "HEY WHITEY! WHERE'S YOUR HAT?!"
- The chef's reaction upon learning that Al just sent back his meal and called it "low-grade dog food".
Chef: Dog food?! I'll show HIM dog food!! *grabs meat cleaver*
- Al to a woman at the party: "Hey, baby, I bet you were something before electricity!"
- After Al bribes the band to play something more upbeat, his dancing is epic.
- "Dance of the living dead!" And Al's there to toss some money around and liven things right up.
- Al steals Judge Smails' wife and starts dancing with her:
Al: You're a lot of woman, you know? You want to make $14 the hard way?
Smails: You, sir, are no gentleman!
Al: Yeah, I'm no doorknob, either!
- The guy who vomits through the sun roof of someone's fancy car. When the couple who own the car leave the party, the man sits in his seat while a squish sound effect plays and the woman coughs in disgust.
- The Baby Ruth in the pool. Man, it looks so much like poop. Has a literally knockout punchline, too, for poor Mrs. Smails.
- Al taking the controls of his giant cabin cruiser and rampaging all around the bay trying to get his boat to Smails. He's an absolute font of One Liners in this scene:
- Blowing by Smails the first time around, "Hey, SMAILS! My dingy is bigger then your whole boat!"
- (after nearly getting run over by a Grumman Super Goose taking off) "I almost got head from Amelia Earhart!"
- (Running into a jet ski formation) "What's this, Hell's Angels?!"
- And of course, the classic, "Hey, you scratched my anchor!"
- Danny has sex with Lacey Underall, and Judge Smails comes home to find them half naked. He goes ballistic, trying to hit Danny with a golf club. At one point, Danny locks himself in the bathroom, where Smails' wife is taking a shower. Startled at first, his wife quickly gives him a seductive look.
Mrs. Smails: Elihu? Could you come and loofah my stretch marks?Danny: (makes some sort of coughing sound)
Guest: That must be the tea.
- And while that is going on, Smails is slowly hacking through the door, with the golf club.
- After this, Judge Smails, who continues to chase Danny, inadvertently pushes a butler at a stair railing, causing him to drop the tea that he's holding, where it falls in front of four elderly guests, who are unfazed by this.
- The bishop's (near-)perfect game of golf, all the while extolling the virtues of his faith...until he botches the final putt.
- After the incident with Lacey, Judge Smails asks to see Danny in his office. But the two can't quite see each other because a giant desk lamp is in their way. After repeatedly trying to peer around the lamp, Smails just knocks the lamp off his desk.
- "Your honor, your honor."
- The club's staff betting on whether Judge Smails' nephew picks his nose, and then they bet on if he eats it.
- The epic feud against the gopher, which reaches an explosive peak at the end.
- Two words: FREEZE GOPHER!
- After Al wins his bet against Smails, he cheerfully tells him to pay up. Smails refuses, and Al motions to a pair of goons standing nearby:
Al Hey, Moose, Rocko! Help the Judge find his checkbook!
- "HEY, EVERYBODY! WE'RE ALL GONNA GET LAID!"
- Followed by much rejoicing.
- Really, anything involving Chevy Chase in the sequel.
