Seven, Sunday, 8.30pm ★★★ The initial impression is that Ricky Gervais’ send-up of crap British sitcoms, When The Whistle Blows, has sprung to life. Broad doesn’t begin to describe the vein of humour mined when two old ladies pretend to eat pet food to get their dog to eat. But gradually the onslaught of gags, and the bawdy humour, start to become funnier and funnier. Tonight Mrs Brown mishears a plan to put her dog in a home, and assumes her children mean to put her in a home. Sophisticated comedy it is not — but it is cumulatively very funny.
