and believes himself to be completely rational, and is convinced that he is in complete control of everything and everyone around him, going as far as to label himself a 'golden god'. In the season 12 finale, Dennis reveals to the rest of the gang that he has an infant son, and moves to North Dakota to raise him. He returns to Philadelphia in season 13, supposedly supporting his family from a distance. Rob McElhenney as Ronald "Mac" McDonald, co-owner and self-proclaimed bouncer of Paddy's Pub. He is Charlie's childhood friend and Dennis's high school friend. The son of a convicted felon who has been in prison for much of Mac's life, he frequently attempts to demonstrate his toughness and refers to himself as the "sheriff of Paddy's".
