Vincent Pastore, best known as Salvatore “Big Pussy” Bonpensiero from HBO’s “The Sopranos,” will be the special guest when comedians Tony Liberati and Goumba Johnny perform at The Treehouse Comedy Club at the Westport Inn on Saturday, Dec. 30.

The show is a combination of stand-up and audience participation, where guests will have the chance to act out some scenes from “The Sopranos” with Pastore, while also enjoying some of his humor. You don’t have to be a mobster to act with him, but if you want some tips, Pastore knows a guy who knows a guy. (He’d tell you his name, but he can’t, because then he’d have to kill you.)
