Soprano's Tony Sirico real life tough guy-- General public shocked

According to The Smoking Gun, Tony Sirico, the actor who portrays Paulie Walnuts on The Sopranos, didn't have to stretch his acting muscles too much to portray his on-camera role. In the '60s and '70s, Sirico was apparently a mafia-connected thug who spent time in Sing Sing and other prisons of that caliber after he was convicted on felony weapons possession charges. I love it. There's nothing I like more than a little authenticity in my mafiosos. Sirico is also quoted as saying he would "carve his initials" in the forehead of a disco club owner that he had a beef with. Although hilarious and pretty cool, I'm a little frightened, and this is probably the one time I wouldn't want a celebrity reading my post about them. I mean, Paulie beat up an old lady!! Does that picture look like it's looking at me...?
