There's only 21 days / 504 hours / 30, 240 minutes remaining until we celebrate the birth of Jesus by exchanging extravagant gifts with people that we don't even really like a good 360 days of the year - it is tradition, who are we to break it?!  This day three weeks you'll be lying back on the couch after a feed of turkey, seconds, wine, pudding, turkey and cranberry sandwiches, tea, trifle, Cadbury's Roses, and shared your fair share of bad jokes and embarrassing tales. Maybe, just maybe, your Christmas dinner will have passed by without a hitch or an argument. It's time to keep calm and get your sh*t together, Christmas is just around the corner... Here's a list of 21 things you'll need before the big day.  1. Christmas Underwear Everyone needs to greet Saint Nicholas and ring in the New Year in a new pair of briefs. It’s the least we could do for the man considering he dragged his sack down the chimney. Sack of presents, obviously. MIND OUT OF THE GUTTER, PEOPLE. 2. The Christmas Coat Your 'Sunday Best' simply isn't good enough and the neighbours need to know you've upped your game from last year. 3. Christmas Mass Outfit Because you need something good for under that good coat. 4. Festive Pyjamas The fleeced variety from Penneys. Splash out like the mad yoke that you are and purchase the matching fluffy socks while you're at it. 5. Mistletoe No single woman should leave the house without it. Seize every opportunity of a shift this Christmas. 6. Tin of Roses It isn’t Christmas without a standard tin of Cadbury’s Roses underneath the tree. Note: People that put the empty wrappers back in the tin, you are the worst. 7.  A Cinnamon Candle If you skimp on the decorations this year at least it will smell like Christmas. 8. Guinness Six packs that sit there all Christmas for 'the visitors'... that never call. 9. Crackers We’re fond of a bad joke and who doesn’t love a miniature torch keyring? 10. Matching Hat And Scarf The last time you wore a hat and scarf was in fifth class, but it feels like the right thing to own. 11. Fresh Cream Sure you can never have enough fresh cream. A drop in the vegetable soup (because it's fancy and you do fancy things at Christmas), the trifle and, of course, the Irish coffees. 12. Brandy Cream For when the fresh cream runs out. 13. Order The Turkey This bird is a necessity in every kitchen Christmas day. 14. Potatoes You need to ensure your dinner consists of every type of potato, start stocking up now. 15. Two Puddings One for the house and the other for 'the visitors'. 16. Selection Boxes That you’ll hide from yourself and find next year. 17. The Good Tin Of Biscuits You can always rely on a tin of Fox’s Classics or the nice Scottish shortbreads. 18. Snowballs And Teacakes For when the fancy biscuits run out. 19. Shloer It is simply not Christmas if there is no Shloer. End of story. 20. Michael Bublé's Christmas CD You buy it every year. It's not Christmas without a collection of played out Christmas tunes from the world's smoothest crooner. 21. The Christmas Haircut It's been spectacularly featured in every annual family photo. It's a tradition.
