Do these skits actually speak to Californians in general or LA-ians more specifically?
Any Northern Californian worth their salt will state that it is focused on SoCal only. 
(Redwood City, baby!)
It’s a certain subset of affluent white West LA.
I was born and raised in SoCal (don’t currently live there) and I get the stereotypes they’re portraying, but I don’t think any more so than someone who didn’t grow up there, if that makes sense. I don’t recall, for instance, talking overly much about the routes I take (though we do put “the” in front of the freeway number). The accents make me laugh but I don’t relate to them anymore than anybody else who is familiar with the valley girl trope.
I enjoy them, if for no other reason that I enjoy hearing references to familiar places that I miss 
I never found the sketch funny and assumed it was because I’m not from Southern California.
Southern Californian, find them hilarious. Every once in a while Husband or I will realize that we’ve diverted a conversation about a place into a conversation about how to get to that place, so we slip on their overdone accents.
It’s a takeoff on SoCal kook lingo (joke). What is a kook, well, it’s a doofus who looks like something from a Dr. Seuss book while surfing. Here’s a statue to one.
So the “that chick’s got a gnarly rack dude” and the “for sure” (valley girl) is an act.
Like, oh my gawd!! As if!!
Shouldn’t that be ‘fer sure’.
It’s very much a West L.A. (where I grew up) and San Fernando Valley thing.
Lived in SFV for 35 years.
I get it.
I was raised in LA. I recognize what they’re trying to mock, but it isn’t really funny. To me, it reads like someone from New York trying to do an impersonation of people from LA based on one terrible party years ago. It would be like me describing New York based on going to a trade show 15 years ago. I’m sure it be extremely accurate and HI-larious.
Totally!
Mostly LA, but there are some elements in there that apply broadly to CA, like the obsession over certain “authentic” types of furniture, wine, etc. The skit came out of a joking thing the actors used to do after taking a break from NY and going to LA. When they got back, they would do little “exaggerated Californian” jokes amongst themselves, and then later developed it into skit format. I find it hilarious.
SNL does a lot of ribbing of regional accents and behaviors. They love doing Bostonians, Canadians, Mid-Westerners, New Jersey-ites, and of course certain international types, too.
I don’t find it at all funny. It seems to be combining Hispanic telenovelas with Anglo stereotypes. Pick one or the other
I never really got the sketches. The only times I really enjoyed them were when Bill Hader (or someone else… but usually Bill) broke and started laughing. For some reason corpsing is hilarious to me.
It was no Stephon.
I have a friend Stephon, who’s a fairly serious guy. I’m always so disappointed when he says “You know what we should do?” and doesn’t immediately launch into a litany of absurd clubs… while trying not to laugh.
I should pay him to suddenly switch to that accent and surprise everyone:
“New York’s hottest club is: Wesh. Nine-year-old Tokyo pimp Ichiaku Guru is back with an all new hotspot that answers the question, “WHAT?!” This place has everything: Trance, stilts, throw-up music, an albino that looks like Susan Powter, Teddy Graham people. It’s that thing when a guy has the stumpy arms, but with the belly.”
If you like Stephon, turn to the real estate section and read the home description the way Stephon would.
This home has EVERYTHING…
That is a great idea! We used to laugh out loud reading the Art Galleries’ descriptions in the New Yorker: “A wall of rubber bands evokes a nostalgia for Middle America in the post-war years, with melted Sculpey laid on with a broken garden trowel symbolizing the Cold War.”
I have a friend who does quirky humor, I’ll tell him.
He’s been known to find humor where no one else would. He’ll hit garage/estate sales in a small town, pick up multiple years’ worth of the local high school yearbooks, then make up stories tracing the students, from shy freshman to wild senior.
It’s almost like the National Lampoon High School Yearbook Parody. And brings back memories of following the fictional kids of Estes Kefauver High (who also showed up in the National Lampoon Sunday Newspaper Parody).
