Yeah, you already knew Fox News host Bill O'Reilly could be a volcanic asshole on camera, because he explodes at people all the time. But it's still fun to watch O'Reilly thoroughly lose his shit in this old clip from his Inside Edition days, which resurfaced on the Web tonight. You have to feel for whatever poor soul wrote the script for O'Reilly's teleprompter. Video — including the exclamation "Fuck it! Do it live!" — after the jump.
