22 - The Office Xmas Special
Described by Richard 'Four Weddings' Curtis as 'the greatest programme I have ever seen', The Office went from cult hit to comedy classic over the short course of two series and a Christmas special. The brainchild of Ricky Gervais and Stephen Merchant, the spoof fly-on-the-wall documentary observed life in the Slough branch of paper merchants Wernham Hogg. Gervais might have run the show (at least until David Brent was given the boot), but it was Tim and Dawn's will-they, won't-they flirting which provided the genuinely romantic ending we'd been hankering after since the beginning of the series.
