The Berlusconi Show 7pm, BBC2 Italy's prime minister is generally seen as so bizarre that it requires an act of will to remember that he is in charge of a European country; the older he gets, the more determined he seems to behave like the more decadent Roman emperors. In this terrific documentary, Italian-born journalist Mark Franchetti returns to his homeland to consider the Berlusconi phenomenon. After 25 years away, Franchetti brings an outsider's bemusement to his subject, but retains sufficient insider understanding to be able to explain Berlusconi's enduring, infuriating and apparently indestructible appeal. The Man Who Ate Everything 9pm, BBC4 A delicious documentary you'll want to savour at leisure: Andrew Graham-Dixon presents an utterly charming profile of late Great British eccentric Alan Davidson, and his equally eccentric Oxford Companion to Food, described by QI creator John Lloyd as "the greatest book in the English language". This "bible of the fusion movement" contains exquisite, witty little essays on every foodstuff imaginable, from Spam to lollipops, aardvark to warthog. And an entry on washing up. Though it contains no recipes, it remains a virtual "portrait of the whole human race in all its ingenuity". A treat. Mad Men 10pm, BBC4 As the end of last week's episode hinted, the Drapers' romantic trip to Rome doesn't seem to have left too many lasting benefits as Betty is further intrigued by Governor Rockefeller's man Henry Francis. Don, meanwhile, when he isn't being awoken in the middle of the night by new buddy/overbearing boss Conrad Hilton, also has his eye on someone else. Someone not particularly surprising. His sneaking around, not for the first time, somewhat complicates affairs both in the office and at home. Damages 10.45pm, BBC1 Has Patty done a bad thing again? That's certainly the impression tonight's episode leaves you with, as we're offered more glimpses into the investigation of Tom's death. As for proceedings elsewhere, it's mostly about the money as Patty tries to force Louis Tobin to tell her where the cash is hidden before he's sent away to jail. Louis, though, is more worried about his son, Joe, who's hit the bottle in a big way – a spell in rehab beckons. Plus Patty meets her estranged son for lunch, and Ellen cuts off the money supply to her sister.
