The whole thing read to me like a Seinfeld episode - Kramer accidentally kills a whale off the coast of New York, and with the show having made dozens of Kennedy references, hearing of a Kennedy dumping a bear in Central Park would fit right in.
So this doesn't feel even like an own to anyone, more like a parody, a comedy. And in the context of it actually happening 1. in the setting of probably the most famous one, 2. with a character from the exact family they've referenced many times over and 3. with the same type of bizarre things happening to wildlife one of which has been one of the most famous episodes.
To me, as a lib, it feels like the best Seinfeld/Curb Your Enthusiasm episode that's never been written.
Edit: Now that I think about it, the story even came out because he told it to Roseanne Barr, writer of most popular sitcom just prior to Seinfeld, notwithstanding her interminable slide, with her just staring at him incredulously throughout, the whole thing feeling like a Curb Your Enthusiasm scene. Honestly, at this point Larry David is definitely thinking to himself that he could never have written anything this Larry David.
Edit 2: I completely forgot that his, Larry David's, wife in Curb Your Enthusiasm is RFK Jr.'s actual wife. At this point I'm about 80% sure that multiple Seinfeld and/or Curb episodes were actually just Kennedy misadventures in disguise.
