Robin is famous for one of the many things he says to Batman that start with the word “Holy.” Robin would say these things when things were really bad, and he would usually ask, “Batman, what do we do now?”
Robin says things like “Holy Hamlet,” “Holy Hollywood,” “Holy Jackpot,” “Holy Jet Set,” “Holy Shucks,” “Holy Cosmos,” “Holy Iodine,” “Holy Cold Creeps,” and “Holy Houdini” to Batman. In the 1960s Batman TV show, Robin was played by Burt Ward, who had a nasal voice and would say “Holy” in Robin’s place. The catchphrases, which were often related to the story, became popular and were used a lot in everyday speech in the United States.
