I was curious what this was because I don't think I've ever heard Zuckerberg say anything that was either remotely or intentionally funny:
Mark Zuckerberg: "Twitter is such as mess — it’s as if they drove a clown car into a gold mine and fell in."[1]
It's seems to be largely anecdotal but a funny comment none the less.

As long as there are no follow-up questions...
SV hubris is its own thing.
