Oooh, this one takes me back... once upon a time this was the Most Asked Question On T'Interweb, you know. There was a time you couldn't log in without seeing someone ask this question, of course it were all fields round here and you could buy eight hundredweight of toffee for tuppence ha'penny... oh yeah, anyway... there isn't anything *specific* he says to make people lie down (apparently it's just nonsense syllables), it's "Just" meant to suggest the *power* of language. It's like that Monty Python sketch about the funniest joke in the world, that kills anyone who hears it - it's the idea of words having that effect that matters, even though if you translate it, it's basically gibberish.
