Musk aims to be funny to people he doesn't know on twitter using memes that weren't that funny 5 years ago.
I genuinely don't get it. He's shockingly not funny considering how hip he is for his age.
It's a style of humour unto itself. The lack of humour is itself humorous. The real question is whether or not he thinks he is being directly humorous or ironically humorous. I wouldn't be surprised if it was the former. Plus he's rich so people probably laugh at his jokes regardless.
He thinks he's being ironic, but that isn't enough.
Stay mad. What colour is your hair btw?
What color would Elmo's be if he didn't dye it or plug it?
