Lol, thinking about this while playing Cod Blops, on that Nuketown thinking, what would I do if I had three days until the nuke striked.
Day 1. Search, get all the food in one house, then get ALL the Fake people/minifigures/whatever and put them all in the house Or they would die and I'd be lonely.
Day 2. Screw around as much as I can.
Day 3. Find the Led Fridgerator and Indiana Jones it, and survive the explosion and whatnot.
Day 3 Alt. Ride a bike into the center of the bomb clinging the Bell
*ching* *ching* *BOOM*
Then respawn
