Schizophrenia for Dummies

So ventriloquism; surely one very very small step away from multiple personality disorder? I mean, to be objective about this, take away the puppet and what do you have? A grown man or woman talking to his or her hand, and the hand quipping back. Not only that, but this hand even has it's very own wants, needs, goals and quirks. It's pretty scary stuff. And as an audience we laugh it off when, for example, Emu launches into Parkinson's groin for the third time that night. But hello? I think Rod is involved somewhere along the line. All I'm saying is that anyone who chooses to spend their working life conversing with a hand they've shoved up a stuffed animal concerns me. Deeply.
