Scorsese's dad in Goodfellas

I know his dad is hardly in the film but does anyone think he was just brilliant. Two of the my favorite scenes in the film are because of him. When a certain person is taken care of he has the best line 'and that's that' and the phone call scene with De Niro where he just talks around the subject without really getting to the point even though you know what he's talking about. Pesci in The Irishman had some traits which reminded me of him.
