Inspired by the " you have 10 minutes left to live…" thread…
You know for sure that earth will be hit by massive astreroids in next 15 hours, and it has been concluded that resulting tidal waves, ashes,quakes … will kill all life in earth in subsequent 9 hours…
So you have 24 hours left to enjoy life…
No, you don’t have a rocket to escape from earth ( where will you go , by the way )
How will you spend your last 24 hours ??
A certain someone from Florida needs to get a plane ticket RIGHT NOW.
You know who you are.
I assuming that if this scenario did happen, transportation (air travel, train, etc) would all come to a grinding halt, so going home (2000 miles away) is out of the question. I’d probably get together with some of my closest friends and just drink some beer and talk… not much else to do really.
Pray
Apologize to some people
Drink maple syrup straight from the bottle to gross out my family one last time
Large pizza with triple anchovies… or maybe coq au vin… popcorn with lots of brown butter
Hm. Maybe I’ll do all that now (<Scurries off>)
I would get together with friends get totally shit-faced and pass out. Hopefully death will come while I am passed out.
Somewhere in there I would totally get naked and run up and down the streets screaming my head off about the martians trying to butt rape me.
Heroin. I’m going to go score and shoot up heroin for the first and last time ever. It’s been described to me as feeling like a full body orgasm, and I gotta try that once. (My current plan is to wait until I’m diagnosed with an incurable illness or I hit 90 years old; either way I won’t care much if I become an addict.)
Honestly, I’m not sure I’d *want *to be around friends and family. We’d probably make each other feel worse - more terrified and more sad - than if we each just wandered off into the woods and hugged a tree in solitude.
Go buy a pack of cigarettes.
Take the day off from work.

Go tell Bush that this was the real WMD Saddam had been hiding!!
Yeah, it would involve a shitpile of food, a lot of alcohol, and probably some sex with someone I shouldn’t.
I see a cafeteria, 3 Heathers and a Veronica talking about a lunchtime poll, and some nerdy guys saying, “Holy shit, Heather number 1 just looked right at me!” but I digress…
I’d just cuddle up with my baby, drink a lot of wine, and finish with a bang!
It’d probably end up by me shitfacedly attempting to shoot the asteroid down with fireworks.
The path leading to that moment, though, would probably start with an MPSIMS post.
Sounds like a good time for a long-overdue Sacrament of Reconciliation (Confession), so I would look for a priest and hope the line’s not too long.
Go fishing. Preferably in Hawaii.
Pray, hug my sons tight and tell them how much I love them, call my parents and sisters and tell them the same, make love with my wife, start a SDMB thread, “I Pit the End of the World!!!”, and write one last check to the Democratic National Committee. 
Having been a teetoatling vegetarian for decades, I’d start with a case of wine coolers and an English mixed grill. Then ham & pineapple and wine. Then deep fried turkey skin and more wine. Then Irish coffee.
That will kill me before the world ends.
Realistically, I’d probably spend at least the first 6-12 hours desperately trying to figure out some infinitesimally small chanced strategy that would result in my family and I surviving the catastrophe. If I went into such-and-such a basement or cave, or such-and-such a mountain top, with so much supplies and some weapons, etc.
