Michael Ian Black gives co-host Tom Cavanagh a marvelous account this week of his fictitious rivalry with the actor Ian McShane. Black spins a straight-faced tale about heroically landing himself a role on Deadwood, only to come down with laryngitis and have McShane conspire to take him down. Our hosts eventually get around to reviewing Nabisco’s Lorna Doone Shortbread Cookies, which they deem lightweight compared to Walker Shortbread cookies It’s Shortbread 101, as Black puts it, and Walker’s is deep-cut shortbread. This occasions much talk in oozy Scottish accents and the revelation that Black is going to make afternoon tea cool again.
