How dey do dat

Magician slang for common folk who wonder how their tricks are performed. Used by magicians Tony Wonder and G.O.B. on the television series Arrested Development.

Tony Wonder: "The 'How dey do dat’s' ate it up."

G.O.B.: " Oh, poor Michael. You do not think like a magician. Such a 'How dey do dat.'"
