@JGoldman10,
If you thought The Onion Movie was a parody of pop culture, then wouldn't you think that The Onion publication was a parody of news?
If you looked at their website and see the headlines, it is very clear that The Onion is comedic in nature.
Here are their current headlines:
*John Bolton Asked To Leave Condo Board Meeting After Repeatedly Advocating Bombing Isaacsons
*Working In General Vicinity For 8 Hours A Day Misinterpreted As Friendship
*Panicked Ken Burns Worried He In Too Deep With 17-Trillion-Hour ‘The Universe’ Documentary
*Kim Kardashian Tries To Escape L.A. In Rowboat After Realizing Past 12 Years Of Life Have Been TV Show
*Kavanaugh Denies New Sexual Misconduct Claim During Emotional, Pants-Less Press Conference
I'm slowly realizing why you asked for resources on how to write comedy.
