30 Rock

Liz Lemon has a lovely plan to play Secret Santa to a family in need, then finds the presents have gone to the wrong sort of people, and decides to take on the Post Office. Meanwhile, Jack has his holiday plans scuppered by his formidable mother, Colleen, who has moved in and is making his life difficult in the way that only mothers can. To keep her out of the way, he orders the TGS crew to put on a last-minute Christmas special. Sharp, silly and very quick, with Elaine Stritch as the sort of mum you hope never turns up on the twenty-fifth. Pour a sherry.
