Entertainment: Grumpy Old Holidays 10.00pm BBC2
Travel doesn't broaden the mind, according to these old grumblies, who have no problem venting their spleen on the subject of holidays: everything from the trauma of packing to the ritual of airport security checks and the horror that is other holiday-makers.
They're so vitriolic, you wonder why they bother trying to get away from it all - especially when there's a flight involved. Apart from Michael Winner, of course, because he recommends hiring your own jet (a mere Â£18,000 for a round trip to the south of France) or, on long-haul trips, "suffering bravely" in first class. Those of us in "cattle class" may prefer Jane Moore's suggestion that airlines should measure a traveller's bottom in the same way they measure their hand luggage to make sure it's not too big to fit on board.
