Rob Long, one of the funniest writers in Hollywood, recounts the dangers of taking humor out of context; mad, unfit for civilized society, context:
Every writer – well, every comedy writer – has made this mistake. You're at work, and you're laughing with your colleagues, about something – usually what we call a "room run" – a joke that originates entirely in the writers' room, one that's usually so objectionable, so foul, so indefensibly cruel and wrong and ugly, that the entire room is paralyzed by laughter.
Evil, dirty laughter.
But it's funny. Hilarious, actually, to you. So when you get home to your wife or husband or boyfriend or girlfriend, you know, you want to share your day. Share the little moments of joy you experienced.
