The writer and producers of a Broadway play that references the legendary “Who's on First” baseball sketch by Abbott and Costello are safe at home on accusations of copyright infringement.

Southern District Judge George Daniels found that the heirs to the famed vaudeville and Hollywood comedy duo failed to state a claim under the copyright act against the producers of the dark comedy “Hand to God.”

“Hand to God” mimics a one-minute and seven-second dialogue of Bud Abbott and Lou Costello in which Abbott flummoxes Costello with a first baseman named “Who,” a second baseman named “What,” and a third baseman named “I Don't Know.” The routine was performed by Abbott and Costello in two films, “One Night,” and “Naughty Nineties,” as well as on the radio, including on “The Kate Smith Hour.”
