Silicon Valley,while hilarious,has tons of invaluable business lessons.I think I could probably even say it's one of the best series about business. It covers absolutely every aspect of building, growing, maintaining and ultimately selling a business.
Mercifully, I've avoided any conversations like the Season 1 finale, but I think we all laughed because we recall some absolutely ridiculous rabbit hole we went down at some point. Once in a while you learn something surprising (which just reinforces the behavior), but mostly you just feel foolish. Especially if you get caught doing it.
