A recent book, "The Brotherhoods," by Guy Lawson and William Oldham, although not nearly as good as Selwyn Raab's "The Five Families," does provide a bit more detail about Gaspipe Casso's lunacy, including insane stunts he tried to pull off in prison. Louis Eppolito, one of the two crooked detectives who are the nominal subjects of this book, appeared in "Goodfellas" in a bit part as "Fat Andy," one of the guys Henry introduced in Sonny's restaurant near the beginning (Eppolito's one line was, "Howya doin', guy?").
DC, another story I read about Casso's nickname was that his father had a neighborhood racket of diverting gas pipes from paying customers to others so that they wouldn't have to pay. This story is too ridiculous to believe.


Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
