1.) Never, humans will never realize mother earths dirty secret.

2.) Well, he has no children as he dies; His children in a nearly parallel dimension do figure out the earth is triangular, but you are giving no point of reference to base the "amount of years".

3.) When smoky the bear comes, saving his dirty life, then leaving green slime at humans' doorstep.

4.) That question obviously doesn't make sense, a trick question if you will. "One lifts his rifle to fire, and the other ducks behind a boulder" This couldnt have been referring to humans, as we don't have the mental capacity to spawn "ducks" yet. However, these two "people" must have been an alien race, or more likely socks in bad lighting.
Assuming you do not speak of humans, the contract will be struck on 2013, with 200 kilowatts, effectively sending the contract back into the past, on Feb. 30th, 2012.

5.) When the big 'ol boulder sings.

6.) Half the men who weren't presents.

7.) Intriguing question. Yet a circle has infinite vertices. Too much for any program to calculate, as it is infinite. Assuming you can pause the program in time, before ram fills, with a 3.0ghz pent 4, and 2gb of ram, about 10,723,054 vertices, -500 vertices for each koala in the room, as the texturing and colors will increase calculation time, and -300 for each albino koala, as you can use a lower quality texture because of the simple nature of albinos. Depending on the program, give or take a few.

Yay, you got 6 out of 7 right!

*Shakespeare gores you*

Up.
