I feel like there's a minimum "due diligence" bar to meet though before asking, otherwise it comes across as "I'm too lazy to google the reference and connect the dots myself, but can someone just go ahead and distill a nice summary for me"
In this particular case, I was out of the loop regarding the clever analogy myself. I'm now a tad smarter because someone else expressed lack of understanding, and I learned from responses to this (grayed due to downvotes) comment.
