Not that Macaulay really cares about what other people think of his mild weirdness. Sure, he might get booed off stage with his pizza band, but that's just how it goes for a real artist with real ideas. The peanut gallery will never appreciate them. Want another example of Macaulay Culkin's eccentric side? Well, how about his obsession with tongue twisters?
You know the kind: things like "she sells seashells by the sea shore", repeated enough times until your mouth explodes. Actors are often fond of them as a warm-up, but Macaulay was way more than fond. He was so in love with them that he invented his own: "Heidi was her name, hiding was her game when Heidi hid horses halted....". Not bad, although he could have just used his own name for almost the same effect.
