It's dumb how so many people are throwing away the nuance of how light the joke is. Instead of talking about the intensity of the joke, they take a stance that attacks comedy in general. Because the joke itself isn't offensive enough to actually provide a good reason for any reaction. So, it becomes a vague "any joke about" thing.

I can guarantee if you told someone the story without the context of the joke, their mind would jump to it being a way more visceral joke. Then when you finally filled in what the joke was, it was be very underwhelming lol
