"Holy..."

The lines in the 1960s TV series were uttered by Robin actor Burt Ward and were directly related to the plot; for example, "Holy Graf Zeppelin!"

[1][2] In his cameo on the Arrowverse crossover "Crisis on Infinite Earths", Burt Ward exclaims, "Holy crimson skies of death!"

[3] Bradley J. Ricca, comic book scholar at Case Western Reserve University, suggests that: "Robin exists as a media entity inextricably linked with Batman and shares nearly as much ubiquity in American culture".

[4] American author David Shields notes how much in contrast Robin's "Holy..." outbursts, his alliteration and assonance, his fast riffs were to the laconic Batman.

[8] Image Entertainment paid homage to Robin's quips with the title "Batman: Holy Batmania" in a 2004 2-disc DVD release containing four documentaries discussing the sixties TV series.
