why do they send him anywhere?
I may have missed a couple of lines of narration in the film that explain this, so please be patient with my ignorance on the matter --
Why do they send the guy backward? All he does while he's there is flirt with the woman. Was he supposed to be doing something else that would have prevented Paris' destruction in some way?
Why do they send him forward? While he's there he talks about giving the future-people some sort of information that will help them, but what could that be? And who would it help, and how?
Oh yes it's Laaarry Holmes/and the feeelin's right/Oh yes it's Laaarry Holmes/what a fight
