Humor depends on a shared worldview and set of assumptions. People have known this forever and even riffed on it - like Steve Martin had a funny bit where he pretended to tell a “plumbers joke” based in the fake premiae that there were a lot of plumbers in the audience. Of course the joke fell flat which was the whole point.
If SNL were to tell a biteme joke or a cameltoe joke it would fall just as flat and for the same reason - no “plumbers” in tge audience.
I haven't seen this bit by Steve Martin but I know his style of humor so the way you wrote it, it made me laugh.
“This lawn supervisor was out on a sprinkler maintenance job and he started working on a Findlay sprinkler head with a Langstrom 7″ gangly wrench. Just then, this little apprentice leaned over and said, “You can’t work on a Findlay sprinkler head with a Langstrom 7″ wrench.” Well this infuriated the supervisor, so he went and got Volume 14 of the Kinsley manual, and he reads to him and says, “The Langstrom 7″ wrench can be used with the Findlay sprocket.” Just then, the little apprentice leaned over and said, “It says sprocket not socket!”
