I don't mean Barbie's Ken, but Ken Williams. And I don't mean the actual guy either, but some of his appearances in the old Sierra adventure games.
There's something pretty silly going on, y'see?
Okay so here's the thing.
Chronologically, we start at Leisure Suit Larry 1. The guy in the white shirt telling jokes in Lefty's bar is supposed to be Ken Williams. Looking at the original source code for the AGI version, he's just "the bore", but the SCI version explicitly calls him "Ken". He also visually matches the Ken who walks up to congratulate you at the end, save for the outfit.
In the sequel, we meet Chief Kenniwauwau. The code again confirms what the art suggests: this is a riff on Ken Williams. So far no foul, it's not like there's a law against two big men named Ken coexisting.
Leisure Suit Larry 3 has the Chief renamed to Chairman Kenneth, but he uses the same sprites as in the previous game so you know it's still him. So far so good. But then in the end Larry and Patti travel to the "real" world and Larry gets hired by Sierra to make the very trilogy you just played. Okay, that's fun.
And then in the sixth game you find the guy from the bar floating around in La Costa Lotta's pool, up to his old thing. He is explicitly identified in the text as the same guy.
Did Larry travel back to his home world at some time? Was it a side effect of whatever happened in Leisure Suit Larry 4 - The Missing Floppies?
Relatively straightforward, really. In Space Quest 3, Roger rescues the Two Guys from Andromeda, flies into a black hole, and ends up near Earth. He lands in Coarsegold, near the Sierra office, and the Two Guys are hired... by Ken Williams.
But there's also a Ken, white shirt and all, who works as a slave driver for ScumSoft™. Again, the code confirms it's him. Again, there's no law that says you can't have two of them.
The fact that Roger can just take the slightly longer way back and take a pit stop on Magmetheus implies to me that Roger's world is the "real" world that Larry ended up in. But at the same time, there's a set for Space Quest 2 at the end of LSL3...
Part the Third - The Rest of It
Also at the end of LSL3 are sets for King's Quest 4 and Police Quest 1. We even see (an actress depicting) Rosella try to climb the (fake) whale's tongue in that scene.
But if you press the forbidden button in Space Quest 1, you end up in King's Quest 1, meaning King's Quest isn't "just" an act. And as the Twitter thread formerly linked above showed, King's Quest appears to share a world, to some degree, with Quest for Glory.
And if Space Quest 3 is set in the mid to late 1980s (local Coarsegold time) since that's when Larry and the Two Guys are supposedly hired, and is mostly set in the same universe as the "real" world if not several star systems away, how can there be a starship Enterprise docked at Monolith Burger?
On top of that, the backstory for Space Quest 4 states that everything involving Vohaul's return is because of an infected copy of LSL4, which was considered lost since forever, and the bargain bin all but spells out that the SQ10 - Latex Babes segment is set in the very far future, considering it has King's Quest 48.
So if Roger traveled to 1980s Earth, specifically 1984 Earth since Mark Crowe has to be there to help with King's Quest 1... well, six more Space Quest sequels isn't nearly enough time for King's Quest to get up to forty eight.
