In order to keep the crowds moving through the exhibits in his traveling show . . . Mr. [P.T.] Barnum posted signs that read: "This Way to the Egress." Eager to view this presumably strange and exotic exhibit, the throngs would push through the door labeled "Egress" -- and find themselves in the street.
