Actually, it's quite a bit more than 53.
According to a notice posted on the employee bulletin board at Seton Hall University's heavy metal radio station WSOU, uttering any band names or playing any songs with the words "devil," "Satan," "God," "Jesus," or "any other Catholic references that are portrayed in a negative light" will result in suspension.
But to take any guesswork out of which band names aren't appropriate for the airwaves at "Seton Hall's Pirate Radio," the management drafted a list of the 53 dirtiest band names that you can never say on the radio, a la George Carlin's iconic monologue about TV.
The list includes such metal radio staples as Cradle of Filth, Cannibal Corpse, Anal Cunt, Morbid Angel, and Deicide, but also a bunch of just-fun-to-say-out-loud outfits such as Adolf Satan, Baby Jesus Hitler, Crucifucks, Jesus Chrysler, Smother Theresa, and, of course, Hell-O.
It's all fairly ridiculous Roman Catholic university stuff, but you'll be quick to forgive once you realize that mentioning Nickleback and/or Justin Bieber will result in a DJ's immediate termination.
