Imagine if a man traveled back in time to shoot his grandmother in the head...
...but in another time line another version of him traveled back at the same time to tell his mother to move in next door so he can shoot his grandmother's twin sister in the back of the head...
...just to startle the first gunman into misfiring and accidentally killing Nickleback. Would it still be worth it even if you had to suck a Zika dick?
