SERIES FINALE: It saddens me to say this, especially about a comedy that has made me laugh so loudly and so often, but this 39th episode is the final fresh installment of the HBO animated series based on the raucously informal and freewheeling podcasts featuring Karl Pilkington, Ricky Gervais and Stephen Merchant. My, I’ll miss this show – especially Gervais’ laughter and Pilkington’s deadpan observations. Tonight, for example, he’s trying to prove to Gervais and Merchant that the longer creatures live, the smarter they become, and uses as evidence a bit of personal observation: “I saw a cockroach playing Pac-Man.” Gervais roars when he hears that – and, watching the promo, so did I. Thanks, Karl and Ricky and Stephen, for a reliable Friday night delight.
