Men Behaving Badly 9.50pm BBC1
This three-part story looks as if it may be the last for the phenomenally successful sitcom: a new series isn't planned, although the writer and stars haven't ruled out the occasional special. The main theme is Dorothy and Gary's attempting to have a baby. Dorothy has secured Gary's verbal agreement, but the whole concept is affecting his performances around bedtime.
Meanwhile, Tony and Debs have moved in together but are having problems of their own. Big changes are promised for Tony's character, but will they be big improvements?
Parts two and three are on Boxing Day and Monday.
