This only served to prove that loud-mouthed simpletons like Joe Rogan will always trump accomplished geeks like Phil. When debating with someone like Joe, it doesn't matter what you say as much as how you say it. Phil assumed he was talking to someone who wanted to be educated, when in reality Joe wanted nothing more than to put a "snobby scientist" in his place. I've seen a clip of Joe Rogan verbally destroying some woman who made a comment at one of his routines. She made the mistake of feeding the flame, and there was no level to which Joe would not stoop to humiliate her.

Phil, never argue with an idiot: they'll drag you down to their level and beat you with experience.

I also just lost considerable respect for Penn.
