I finally saw this on TCM a few years ago and also found it hilarious. Especially the ending, which I won’t try to reveal because I’ve never figured out how to do spoilers here.
It gets a little tougher with time but I still get some chuckles from Abbott and Costello Meet Frankenstein.
If you get Antenna TV, they’re running a 50th Anniversary Special on 29 March, featuring interviews with Max Gail and Hal Linden.
Space Madness and Stimpy’s Invention hold up.
There’s a fine but clear line between finding humor in a harmless slip-and-fall—where only someone’s pride is bruised (funny)—and laughing at an incident that could cause real physical harm (not funny). It’s funnier still if the subject appears to be pompous.
This type of humor has tickled folks for a long time, as this video cap of very old ‘found footage’ shows.
I was expecting something completely different, like “get that bicyclist!”
I know what you were describing; it’s just not something I find funny.
I still laugh when I watch the opening credits of My Name Is Earl, though I’ve seen that car hit him a jillon times.
I think it was Groucho who said the difference between an amateur comedian and a professional comedian is that an amateur thinks it is the height of humor to dress a man up as an old lady, put him in a wheelchair and push it down a steep hill. For a professional, only a real old lady will do.

WHACK WHACK WHACK
True - the mention is in the recruiting scene: “Rape, murder, cattle rustling, rape”… “I like rape!”.
In Young Frankenstein, the scene where the monster drags off Madeline Kahn and rapes her, when her response goes from “No, no” to singing in ecstasy. And Revenge of the Nerds, where the nerd (wearing a gorilla mask) seduces the sorority girl, who thinks he’s her boyfriend. Sorry, that qualifies as rape in my book.
Shakespeare plays can also be adapted to modern times. We saw a version of Comedy of Errors, 35+ years back on PBS, done by the Flying Karamazov Brothers. They threw in modern references (“It’s not what you think! She left by the back door!!!”).
There was a theater company in Seattle years ago that did recontextualizations of classic plays, including several by Shakespeare. In their version of Romeo and Juliet the Montagus and Capulets were rival lesbian softball teams. Their version of Macbeth was hysterical.
They’d have to go some to beat the version done by The Troubies!
My wife wanted to watch Young Frankenstein and neither of us had ever seen it fully (I had seen some clips and bits). It was amusing and wasn’t a waste of two hours but I doubt I’ll make any attempt to see it again. I think a familiarity with the actors and source materials (including having seen a number of early monster/horror films) helped with enjoying it and I’m not sure a random 22 year old would get through it.
I realize that saying that invites numerous “My teenager loves it” comments but I’m still skeptical about the average young adult staying engaged.
We do an outdoor movie night every Halloween and our viewing of Young Frankenstein definitely demonstrated that older folks appreciated the humor more than younger folks. I don’t think the young people hated it, but the belly busting laughter from their elders obviously baffled most of them.
My mom told me about seeing Young Frankenstein many years ago; maybe not the original release, but soon after. She went with a friend about her age. When they got to the line “pardon me boy, is this the Transylvania Station?” my mom and her friend laughed their heads off. They were the only ones laughing.
So some of the humor in that film was dated even when it came out.
It was a parody of a movie that was 43 years old. That’s to be expected. The movie worked so well because for the most part it was filmed as a straight 1930s horror movie. The actors acted like it wasn’t a comedy. Without familiarity of the source material a lot is lost. And yes on top of that Mel Brooks’ references were also dated.
On a depressing note Young Frankenstein was 51 years ago. That’s longer than the time between Frankenstein and Young Frankenstein.
Except for Marty Feldman
