If I could go back in time, I would go to Woodstock and watch Jimi Hendrix preform the Star Spangled Banner with his teeth. I would go see who killed tupac and biggie. I'd go get Kurt Cobain autogragh and watch Nirvana unplugged and Nirvana live at the reading.
I'd go meet Bonnie and Clyde. Then I would go see if O.J really killed his ex wife.
