Just for "something completely different", how about picks for the best Comedic Mob or non Mob movie ?
I'll kick it out with two:

1) Wise Guys-Danny DeVito & Joe Piscopo

2) The Gang that couldn't shoot straight (rumored to be loosely based on the life of Joe Gallo)- Jerry Orbach & and a young Robert DeNiro. (1971)

This was one of the earliest DeNiro roles.Two years later he did Mean Streets,and a year after that Godfather 2.

Best mob comedy? I dont know I always liked Oscar with Sly Stallone. I watch it every Thanksgiving with my mommy

The Fannucci's are, IMHO, the best part of the movie.

Made with Vince Vaughan and John Favreau.

Analyze this and Mickey blue eyes are classics

My Blue Heaven - Steve Martin & Rick Moranis

You took the words right to of my mouth Lou. "My Blue Heaven" was a funny movie.

Another good show was "Prizzi's Honor" with Jack Nicholson and Angelica Huston. It's a "dark comedy" but a comedy nonetheless.

For laughs, 1963 - "Johnny Cool", with an all-star cast. Or the Roberto Benigni film, "Johnny Stecchino", 1991. Might be hard to find a copy, but worth a look.

Another vote for My Blue Heaven, watched it again a couple weeks ago and it still makes me laugh.

I didn't know until recently that Nora Ephron based some of the movie on Henry Hill. She was married to Nicholas Pileggi and used his work from Wiseguy as inspiration. I just never put 2 and 2 together...
