10pm, BBC Two

This excellent sketch show refuses to outstay its welcome: the third episode is also the last. But as a consequence, its hit rate is high, and when it's good, it's hilarious. The pair are gloriously daft but retain a keen eye for absurd modern manners: check their po-faced, all-female reimagining of Only Fools and Horses ("the repetition of the word 'plonker' actually felt quite problematic to us").
