Rush got a real thrill when Fredo blew his cool over being called Fredo. Personally I think he is more like Sonny who was such a predictable hot head it got him killed.
Cuomo was a bad combo of both Fredo and Sonny, an arrogant, hot headed, dumb bastard and it got both of them kilt.
Hail Mary, full of grace, {it helped Fredo when he was fishing}.
