I know it’s a very weird question but I’m genuinely interested to see if anyone has an answer. I’m inclined to speculate that the answer is “no.” If that is the case, I further wonder if that’s a result of social conditioning or more environmental factors? In the former, I imagined it would be considered impolite/possibly sinful. As for the second, I’m alluding more to the idea that life in general would’ve been harder so people naturally would’ve been more serious. As a random example, if you were a young Genghis Khan living in Mongolia where your survival basically depended on enduring the harsh elements and hunting for food, I’d imagine you wouldn’t really have a sense of humor throughout life.
It's a few centuries earlier, but the Early Medieval English loved a bawdy joke. The Exeter Book contains a number of saucy double entendre riddles, such as:
I am a wondrous creature for women in expectation, a service for neighbours.
I harm none of the citizens except my slayer alone.
My stem is erect, I stand up in bed, hairy somewhere down below.
A very comely peasant's daughter, dares sometimes, proud maiden, that she grips at me,attacks me in my redness, plunders my head, confines me in a stronghold, feels my encounter directly, woman with braided hair.
Wet be that eye.
Or:
Splendidly it hangs by a man’s thigh, under the master’s cloak.
In front is a hole.
It is stiff and hard; it has a goodly place.
When the young man his own garment lifts over his knee, he wishes to visit with the head of what hangs the familiar hole he had often filled with its equal length.
The answers, of course, are an onion and a key.
By the 14th Century, we have a whole joke book, the Facetiae by Poggio Bracciolini, which contains gems suchs as:
A young Florentine was going down to River Arno with one of those nets in which they wash wool, and met a frolicsome boy, who, out of fun, asked him what birds he was going to catch with that net of his? “I am going to the Brothel’s outlet,” replied the youth, “to spread my net there, and catch your mother.” “Mind you search the place carefully,” retorted the boy, “for you will be sure to find yours there also.”

A Friar, who was but moderately considerate, was preaching to the people at Tivoli, and thundering against adultery, which he depicted in colours of the deepest dye. “It is such a horrible sin,” said he, “that I had rather undo ten virgins than one married woman!” Many, among the congregation, would have shared his preference.
