Most of my xmasses were pretty tame and not too exciting. Except one year, which was enough excitement for my whole life p much.
One Christmas back in the 90's, we had waited until the evening to open presents so we could do it with my aunt and cousins after dinner. My mom was trying to open a can of that gelatin cranberry sauce and she sliced the palm of her hand wide open. It bled all over the kitchen because instead of cradling it/applying pressure like a sane person, she flailed around for a minute. And when I say "all over" I mean ALL OVER. It was on the cabinets and floor and the food that'd been left out (we tossed it after, yes) and the fridge and everything. Luckily the cran sauce was kind of a dessert and we'd already eaten dinner.
So dad drives her to the ER. That left me (age 10 or 11) home with my aunt and my two little cousins (ages 4 & 5).
I'm cleaning up the gorefest in the kitchen, and then one of my cousins decides to throw a temper tantrum over not being able to open gifts until my mom got back from the ER, and he stumbled into the tree. The tree knocks over and the star at the top bursts, and it's electric, so the circuits are tripped and the lights go out.
I frantically find a candle and reset the circuit breakers. Then I wandered into the living room and suddenly smelled something burning. I thought it was probably the smell of my lighting the candle and ignore it. My aunt takes the little kids into my room for a time-out. They're screaming at the tops of their lungs and crying like there's no tomorrow, probably both from fear and frustration.
Then, the fire alarm starts going off. I run back to the living room and apparently the tree is on fire. It's a fake tree, so the lovely aroma of burning plastic fills the room. I grab a fire extinguisher to put it out (after my aunt tries to throw water on it and I yell at her over it to stop her--it's an electrical fire--yes she's not too bright).
But I had never used a fire extinguisher before, and in case you've never used one, they are VERY VERY PRESSURIZED. When you pull that lever the fucking thing EXPLODES foamy powdery shit. I'd used SHOTGUNS before that had less kick-back than this thing. It bucked up and popped me in the throat and knocked me on my ass. Incidentally it put out the fire, but it also made a comma-like arc of foam/powder/whatever-that-shit-is across the living room and couch.
The rest of the night we were airing out the living room by opening all the doors and windows. It was pretty cold out so we all just kind of huddled for warmth in my parent's bedroom and watched Batman on VHS until they got back. When they did they tripped balls about the mess and sent my aunt/cousins home.
We cleaned up everything until I passed out on the couch. The next morning I opened my presents >_>
Luckily though it was a pretty good haul that year :P
