Doc: "Fifty years of sports statistics. Hardly recreational reading material, Marty."
Marty: "Well, hey, Doc, what's the harm in bringing back a little info on the future? Maybe we could place a couple of bets."
Doc: "Marty! I didn't invent the time machine for financial gain. The intent here is to gain a clearer perception of humanity: where we've been, where we're going, the pitfalls, the possibilities, the perils and the promise. Perhaps even an answer to that universal question: why?"
Marty: "Hey, Doc, if we use the almanac we can use that money to set up think tanks, hospitals, donate to charites and help humanity with our winnings to say nothing of playing the stock market"
Doc: *bug eyed look* "Great Scott! You're right!"
Cut to just outside the Brown / McFly Institute for the Betterment of Humanity Building.
