I think they stole that from Neil Young.
Never mind.
Hundreds of Beavers in a film of very broad slapstick, but there’s a small joke that made me laugh. Our hero has been injured and taken in by a trapper, who nurses him back to health while travelling with his pack of five sled dogs. (The dogs, like all the animals in the movie, are human actors in dog costumes.) Hero and the trapper are bedding down for the night while the five dogs stay up playing poker. The next night looks exactly the same, except there are four dogs playing bridge. The next night there are two remaining dogs playing war. Then there’s one dog playing solitaire.
In Jay and Silent Bob Strike Back, the titular characters are pursued by Marshal Willenholly.
Yeah, that’s an old one. I also saw it used on The Avengers (the British spy show), where Steed visits the law firm of Dickens, Dickens, Dickens, and Dickens.
I’ve always wished someone would have thought to add ‘Boyd’: Boyd, Dewey, Cheatem, and Howe.
I’m just now remembering that Oscar Wilde used a similar joke in The Importance of Being Earnest (1895):
JACK: Miss Cardew’s family solicitors are Messrs. Markby, Markby, and Markby.
LADY BRACKNELL: Markby, Markby, and Markby? A firm of the very highest position in their profession. Indeed I am told that one of the Mr. Markbys is occasionally to be seen at dinner parties.
Let’s go for a holiday favorite - *It’s a Wonderful Life *, after the school dance; they’re walking home, and Mary loses her robe and id hiding in a bush:
Mary: Ouch! Oh!
George: Gehsundheit.
Is it Groundhog Day already?
Okay one from me. Buckaroo Banzai.
New Jersey: “Why is there a watermelon there?”
Reno: “I’ll tell you later.”
No, no he doesn’t tell him later.
In the movie “There’s Something About Mary” Woogie (Dom) was asked how things are going and he responds, “Aww, you know, each day is better than the next.”
Takes a beat for your brain to catch up to that one.
However, Robbie also appeared in 2 episodes of Lost in Space. 
They were also both designed by the same guy, Robert Kinoshita.
Another one from Casablanca, buried inside a very dramatic moment.
Rick and Ilsa are talking having their first actual conversation in the movie. Ilsa says something like, “I haven’t seen you since that last day in Paris.”
Rick responds with his cynical tone. “I remember everything about that day. The Germans wore gray. You wore blue.”
I don’t think it was supposed to be a “joke” but I still laugh every time I watch the scene.
Just riffling through IMDB, the Stooges liked making up names besides Dewey, Cheatham & Howe: I. Doolittle, Hammond Egger, etc.
Little Shop of Horrors 1960.
After Seymore tells Audrey that he named the plant Audrey II.
Audrey - “That’s the most exciting thing that’s ever happened to me.”
Dick Miller (forgot the characters name) - “I’m so sorry.”
The Car Talk guys made an art form of that. My favorites may be the Payne-Diaz family.
In the 1960 movie he named the plant “Audrey, Jr.”
It was in the stage musical (and later movie) where he called it “Audrey II”
From A Bug’s Life, when Flik is looking for help at the insect restaurant. A fly can be heard to say, “Waiter, I’m in my soup!”
From the movie Volcano which came out in 1997:
[Museum personnel are moving paintings from art museum threatened by erupting volcano]
1st. Guard: Man, this Hieronymus Bosch is heavy!
2nd. Guard: That’s because he deals with man’s inclination towards sin, in defiance of God’s will.
1st. Guard: I didn’t mean it like that.
2nd. Guard: Oh.
Lake Placid (1999)
[Upon finding a decaying toe]:
Hector: Is this the man that was killed?
Sheriff Hank Keough: He seemed… taller.
What with the Shyster part they got two jokes in one.
This is not really a joke, as written, but I love Christopher Reeve’s delivery of the final line:
He was a funnier guy than he’s generally given credit for. (I also like his performance in Noises Off.)
