"Where's Elizabeth" is not a question per se, but rather it is an expression men use when surprised. "Where's Elizabeth" is generally said when a man sees a corpulent female and is amazed in some way; but it can also be used when a man sees anything mammoth which is out of the ordinary, such as a lake monster.
I was in the bar last night and in walked a 300-pound girl...and I couldn't help but cry, "Where's Elizabeth"!
