1. Sheridan's not just our favourite character in Two Pints Of Lager And A Packet Of Crisps.
2. She's also the funniest star of Gavin & Stacey.
Remember Smithy's little sister, Rudi?
3. An incredibly talented stage actress.
4. And the best thing to happen to London's West End in the last five years.
5. Her range of facial expressions is exquisite.
6. She's adorable when she wins stuff.
That's her picking up a BAFTA for her role in Mrs Biggs.
7. And she was in a rom com about the invention of the vibrator.
8. But Sheridan can do serious too. Her performance in Hedda Gabbler was mesmerising.
9. She made an excellent Lucie Miller in an audio series of Doctor Who.
10. And her appearance as loveable teacher Jenny in Channel 4's Dates this year was just perfect.
11. But really, Sheridan's at her best when she's making us laugh.
12. Which she basically wins at.
13. Although she's also a pretty good philosopher.
14. And a most excellent server.
15. Her relationship with James Corden was the cutest thing in the whole world ever.
16. No. Her friendship with Caroline Flack is cuter.
17. OH NO. Her friendship with David Tennant is EVEN BETTER.
18. NO! WRONG AGAIN! The fact she's really close to her parents beats everything.
19. Let's revisit those facial expressions.
20. And remind ourselves of the time she stripped off for charity.
21. Still not convinced? She tweets pictures of her pug in cool costumes all the time.
22. Sheridan, you're the best.
