I had enjoyed this Three Stooges vignette (“Niagara Falls”) from my childhood. Recently, someone pointed me to an Abbott and Costello version on YouTube. How strange, I thought; did the Stooges swipe this? Was it their homage to Abbott and Costello, which I assume came first? Come to find out that variations on this routine were a vaudeville staple, performed by many (Wikipedia). (And thanks, Bob, for sending me the related “Susquehanna Hat Company” A &;;; C clip!)
