DR WHO does sitcom! The same time as doing DR WHO on the other side! Cue a generation of short-trousered freaks being utterly baffled by sight of time-travelling hero moonlighting from Tardis for Marks & Gran-authored role-reversal antics. Multiple confusion then arises from MATTHEW KELLY, PATRICIA HODGE and KEITH BARRON turning up. Cue mum wondering what all the fuss is about and why Tristan Farnon is living in a two-up-two-down dump in suburbia. Cue dad wondering where the jokes are.
