That joke is one of the long standing debates among Wikipedia editors about whether any humor is allowed on the site. I know I heard more about it at some point (maybe from a podcast or yt vid) but I saved a link to an oped someone wrote about it. Here's an excerpt:

Wikipedia is a place for learning. As an encyclopedia, we owe our readers accuracy, verifiability, and reliability. We pride ourselves on the fact that when people come here for knowledge, they usually come away with error-free, well-summarized, usable information. But we have forgotten one key element that makes Wikipedia successful – joy. It's not that our editors lack joy – like most of you, I'm here because I love doing this. There's true pleasure in making things a little bit better one edit at a time. But as soon as a smidgen of joy makes its way out from behind the curtain and into the gaze of our readers, it is expunged. We are not, collectively speaking, any fun at all.

I'll cite four examples, but there are others you may remember. For years, a number of editors have waged a battle to keep this simple joke off of Wikipedia – specifically, off of Guy Standing's page. Elsewhere, a dedicated corps of Wikipedians have diligently ensured that Will Smith's introductory biographical paragraph bears absolutely no resemblance to the lyrics of the Fresh Prince theme ("In West Philadelphia born and raised..."), even though he was, in fact, in West Philadelphia born and raised.

I don't remember where but I heard in a podcast episode that Guy Standing does not find this funny. I do, though
