Geraldo Rivera is one of the contestants on this season's 'Celebrity Apprentice,' and he's not doing his image any favors. Prone to know-it-all comments and diva-like angry tirades, his ego is showing in a big way.

From insisting vehemently that his chosen name for the group (Vortex) be used, to insisting that they didn't need the 'Dirty Jobs' guy to do a voice-over because that's what HE does, he's showing himself to be self-centered, pompous, and petulant. More often than not, his teammates seem to be bowing to his desires just to make him shut up. Because if you tick him off...well....watch the video and you can see for yourself what happens!

Just remember, if you ever meet Geraldo, don't point at him. Or touch his arm. Or tell him what to do. Or tell him he's doing anything wrong. Or do any of the many, many things that seem to make him mad. Sheesh! It sure makes for good drama, though. And he hasn't been fired yet, despite the fact that his teammates keep offering him up to the Donald!
