About 40 minutes into Cirque du Soleil: Worlds Away, I swear I saw a Lycra-clad Ming the Merciless brandish a paella pan brimming with something red. I thought I was looking at Amfortas' wound in a Las Vegas production of Parsifal. I blinked several times. Both Ming and his paella pan were still there. Ordinarily, one needs the assistance of street drugs or a kaleidoscope to experience a sustained hallucination like this. Maybe it was the 3-D glasses?
