congratulations, after knocking out the a world famous scientist (for reasons i don't care about, you can fill in that blank) you discovered that he recently invented a time machine. yay. what will you do with it? go back and buy a lot of stock for a company to become rich, go back and adopt a dinosaur, shake hands with your long lost ancestor, or something that i didn't think of or was to lazy to type. by the way, the time machine only has enough energy for a round trip, so choose carefully.
