[Tifoso]

EZ, I loved that one. Historically, not any basis in reality but some great Mamet gangster dialogue.

Ness: I'm going to see you burn, you son of a bitch, because you killed my friend!
Frank Nitti: He died like a pig.
Ness: What did you say?
Frank Nitti: I said your friend died screaming like a stuck Irish pig. Now you think about that when I beat the rap.
[He runs a comb through his hair and walks toward the door. Ness, enraged, grabs him from behind and pushes him past the door]
Frank Nitti: Hey... hey!
[Ness propels him toward the ledge]
Frank Nitti: Hey!
[Ness pushes him off the roof. He falls, screaming]
Ness: Did he sound anything like *that*?

In reality, Nitti committed suicide by shooting himself in the head. Ah, movies.
