I had a dream last night that I was a nerd

Last night I dreamt that everyone on Earth was going to die and there was nothing we could do about it. Everyone handled the situation differently - a number of senior citizens where I was got all dressed up and had an extravagant dinner at the fanciest, most expensive restaurant around. Some people just couldn't admit there was no way around our demise and tried to convince everyone that they had a plan to save us. I found myself walking around, observing the different reactions. I was scared and sad and I slit one of my wrists in an effort to speed up the process - I certainly didn't want to be the last one to keel over and die, watching everyone else do the same first.

After some time, those of us still alive noticed that as the sun was rising over the horizon, nobody had died recently. We began to wonder if we actually weren't going to die after all - 99.9% of the world died, but we were the chosen few who didn't. I checked my wrist and instead of the group of bloody slashes I'd seen previously, there were a few faint scars where I'd quickly healed.

Looking around at the others that were left and who had conveniently gathered together in some sort of town square, I didn't think about why we were saved and the others weren't or what to do with all of the dead bodies or how were we going to choose a group of leaders. No, what I yelled out to the group was...

"This gene pool is way too small for effective repopulation!"
