There’s an old maxim that states that everyone in show business is fake. The traditional interpretation of that is that everyone in Hollywood is ready to be kind to your face, but stab you in the back and probably piss on the wound. That may be an exaggeration, but in the case of these 6 comedians, though, they really are fake. As in literally fake. Their public personae are carefully crafted, and you only occasionally see the real person behind it. Most of the time it’s just an extension of the person’s actual personality, but some of them are completely and totally fictitious people. For example, Bono is an experimental attention-seeking robot. Or take Neil Patrick Harris, who is actually a shaved ferret. You had no idea, right? Here are six comedians that almost never break the fourth wall to reveal their true selves.
