My first christmas with my dp, and we wanted to impress!
We had my new MIL and FIL there (he had dementia) and my granny and parents. All started beautifully, until the oven fan broke down and the turkey was still raw after seven hours! It was my first ever year making christmas dinner, in my efforts to keep the party spirit going we decided to keep the drinks flowing! So after a few hours, the food was still uncooked and I noticed my granny swaying she was 96, I walked in the dining room to my pet rabbit running up and down the christmas table (My FIL had got him out of his hutch) my granny had passed out in the chair, my mother in law had 'lost' my FIL and was out in the road looking for him, my mother was laughing rather hysterically about this being a christmas she will never forget, and my father complained endlessly that his legs were giving way from starvation!
So we served half cooked potatoes, and mircowaved turkey, everyone was too drunk to notice, meanwhile my MIL was LAYING on the kitchen floor wailing that she could no longer cope with FIL and we had to step over her in order to serve the dinner - by this point it was dark and a good time to distract everyone with fireworks!
BIG MISTAKE
So we lit the fireworks, and one went into the bin section of the hotel next door, and promptly set fire due to the boxes and packaging. We then had to call out the fire service, and the hotel manager and explain that the hotel was on fire at the back.
At this point I really WAS having a breakdown, FIL was dancing on the table, I had lost my rabbit, my granny thought she was in the war again due to the fireworks - Dad was eating crisps for christmas lunch, and I was very stressed and very drunk. Dad said he was going to stop at the chinese on the way home on his way out as a thank for my efforts, and honestly i vowed I would never ever host christmas ever again! 
It just happened to be my granny and FIL last christmas, I hope they will forgive me
