Fighting off the horde whilst friends and family and strangers and Bill, from accounting, escaped. I fight them all of until I am too tired and fall.
That or...skydiving off the moon whilst getting a blowjob from the sexiest lady alive(to be decided later) and then realising I don't have a parachute.
OR! Cleansing the human race of bad people and then finding out it's a crime, even if they are intolerant, scum, Chavs, murderers, rapist, Bill, from accounting, etc, etc, etc...
