Seriously guys, it turns out there are still butts in the future. They're really real.

Just look at the facts:
• Butts are the most effective mechanism ever devised by evolution.
• Every human on Earth is in direct contact with a butt.
• Butts are funny.

In the year 2525...

The Earth has gone to complete shit, thanks to a race of sentient ass holes. Humans as slaves! Something, something, something, Off World! A stargate! A war is brewing, and something about time travel. LIGHTNING! A butt-person, in the 1980s. A butt-person, in the 1780s.

...The survival of the human risk is on the line.
