Was reading Anthony Lane's New Yorker review of Lord of the Rings: TT, and laughing aloud at several places, including this, which someone else might find amusing, too:

"Gollum, who guides Frodo on his quest, is white-skinned and blue-veined, like a moldering cheese, and his shrunken frame is topped by a triangular head with protruding eyes. Think of Ross Perot after ten years on the Atkins diet, and you're almost there."

PS: Newbies, no it doesn't work quite that well.
