If I could change one thing in the history of Android... if I had THAT kind of power over time and space... I'd go back to 1875 when Android and my great-great-great grandpa had their infamous gun fight in Hog Creek, Montana. It wasn't so much a shootout as it was a legal battle over who was the rightful owner of an antique musket. Pretty dull. I'd go back and change it into a shootout.
