If you don’t yet watch Gogglebox on Channel 4, start doing so now. Far from making you despise our couch-potato nation, it will make you feel great affection for it. Sprawled on L-shaped sofas with comfort cushions or slobbering dogs on their tummies, or sitting side by side on armchairs with a vase of carnations on a doily between them, the programme’s chosen telly-watchers make what must be the most unselfconscious, and therefore genuine, remarks spoken by anyone on air.
