Manfred Mann 's Earth Band 's recording of the song changes the lyrics. The most prominent change is in the chorus, where Springsteen 's "cut loose like a deuce '' is replaced with "revved up like a deuce. '' This is commonly misheard as "wrapped up like a douche '' (the V sound in "revved '' is almost unpronounced, and the S sound in "deuce '' comes across as "SH '' due to a significant lisp). The lyric is actually a reference to a hot rod "deuce coupe. '' Springsteen was fond of classic hot rods in his youth, hence the line "revved up like a deuce, another runner in the night. '' Springsteen himself has joked about the controversy, claiming that it was not until Manfred Mann rewrote the song to be about a feminine hygiene product that it became popular.
