Whatchu gon' do?

So there's this big thing going around about how on August 27, Mars is gonna be the same size as the moon in the sky.
this is, like a castrated medevial choir boy, falsetto. without the tto.
But, after a very extended (drunken) scientific talk with some comrades about the gravitational and possible fatal effects that mars being so close to us would have on our planet, we switched gears a little. and hence, comes this question.
If Mars (or a large meteor or piece of space junk) was throttling towards the earth, and you knew 3 days in advance that this was going to happen, and it was inevitable that everyone on the planet would die, WHAT WOULD YOU DO?
I've posed this question to a lot of people. My favorite response so far was "I'd go to the exact coordinates of where the piece of space material was going to make contact with earth, AND PUNCH IT OUT OF THE SKY..or try to." -Tommy C.

Personally, I'd get an acoustic guitar, a lawn chair, and a small, chillaxed amount of company, and just go to a nice spot where we can watch the impact (and punching) and just play songs and hang out 'till we all burn unmercifully.
It's a nice twist on the age old "OMG WHUT WULD U DO WIT 24 HRS TO LIVE??!!?!!11?//?!"
