You guys nailed a lot of the great moments. I love the whole Fanucci murder, hiding of the gun, etc., and the Don Ciccio murder.
When Vito's with Clemenza stole the carpet. Clemenza acts like he knows the guy, checks under the mat for a key, etc. Vito's onto him and suspiciously looks around. I love the music as they walk down the street. It just seemed appropriate.
When Vito brings Carmela the pear..short and sweet scene.
And I agree the Signor Roberto scene is priceless.

Vito had a certain calm about him that Sonny for sure didn't have, and Michael maybe in the form of "quietness" , but not the "cool" that Vito had.
