Think I fixed most- let me know if there's any I missed. Some I left since they were the first mention outside of the lead. MyCatIsAChonk (talk) (not me) (also not me) (still no) 19:48, 4 August 2023 (UTC)[reply]
You don't really need the citations in the last paragraph of the lead; none of the things you cite are direct quotes, and are mentioned and cited in the body anyway.
I can't find a reliable source that says the dates he worked on it, and the websites that do state it just cite the Seth Meyers interview that's already there. MyCatIsAChonk (talk) (not me) (also not me) (still no) 19:48, 4 August 2023 (UTC)[reply]
"Senior British Correspondent" not capitalized in lead
"including The Simpsons...episode ten)" This should have semicolons instead of commas.
"liberal-bias" Why the hyphen?
"Oliver has also founded" → "Oliver also founded"
"In 2018 on Last Week Tonight" → "In 2018, on Last Week Tonight"
"the rabbit Marlon Bundo" Might wanna mention that he was Pence's pet.
All references are properly formatted, and seem to be to either reliable sources or interviews.

Any reason why there's an external link to The Guardian's articles specifically?
Well, it's a topic in the website, and The Guardian frequently publishes articles related to LWT episodes. If it seems out of place, it can be cut. MyCatIsAChonk (talk) (not me) (also not me) (still no) 20:03, 4 August 2023 (UTC)[reply]
That's all I have, very nice work on this article. AryKun (talk) 13:51, 4 August 2023 (UTC)[reply]
Thank you very much for the quick review, I greatly appreciate it. I would like to take this to FA, but can't put it up at PR since I have another PR open- seeing as you have some FAs yourself, do you think it's in a reasonable state to send to FAC? (Of course, I ask this entirely informally.) MyCatIsAChonk (talk) (not me) (also not me) (still no) 20:03, 4 August 2023 (UTC)[reply]
Okay, I'll be passing the GA. I think that this article is very close to FA quality already; perhaps the only suggestion I have is adding a sentence about subreddits spamming Oliver's images during the Reddit API shutdown. AryKun (talk) 14:29, 5 August 2023 (UTC)[reply]
