1. Tim & Dawn finally get together in The Office Christmas Special.
2. The final scene of Blackadder Goes Forth.
The slow motion charge, the music, and the way the final shot fades into a modern day poppy field combine to make what is arguably the most poignant TV endings of all time.
3. The Doctor and Rose go their separate ways in Doomsday.
4. Rachel's car accident (and eventual death) in Cold Feet.
5. Nana dying in The Royle Family.
When a comedy show takes a serious turn it tends to pack more of a punch than it would in a drama. Seeing usually jovial characters hurting is almost unnerving. This is certainly the case when Nana passes away in The Royle Family, where no one takes it worse than her former sparring partner, Jim.
6. Andy's Big Brother monologue in the Extras Christmas Special.
7. Tiff getting run over in Eastenders.
OK, we've watched this back and it does seem to be one of the slowest car accidents in history, and in real life she'd probably be left with nothing but some minor whiplash and a slightly dirty jacket. But at the time it was VERY sad. Honest.
8. Andy Murray crying after losing the 2012 Wimbledon final.
This was his fourth grand slam final and his fourth defeat, but fortunately Andy hasn't had much to cry about since this moment. He went on to win Olympic gold just one month later, and has since won both US Open and Wimbledon singles titles.
9. Alma dies of cervical cancer in Coronation Street.
10. The Doctor loses Amy and Rory in The Angels Take Manhattan.
11. Del Boy and Rodney get a standing ovation, Only Fools And Horses.
After years of wheeling and dealing, the Trotter brothers' luck has come in after they find a watch that is worth millions. Here they enter their local, The Nag's Head, unsure about how their friends will receive them now that they're millionaires. The following standing ovation is one of the great moments from British sitcom history.
12. Lady Sybil dies in Downton Abbey.
13. When the baby elephant died on Africa.
We're used to Mr Attenborough turning us into emotional wrecks, but we weren't prepared for this. The BBC's Africa showed a mother staying behind to look after her calf, and therefore losing the herd in the process. Sadly it was too late, and the mother was forced to watch her child die, before disappearing into the desert on her own.
