Taken from Your Money & Your Brain:
In the movie Dumb and Dumber, Jim Carrey's Character, Lloyd, asks the love of his what his chances are of making her love him, too.
"Not good," replies Mary Swanson.
"Not good like one out of a hundred?" asks Lloyd haltingly.
Mary answers, "I'd say more like one out of a million."
Exclaims Lloyd; "So you're telling me there's a chance? YEAH!"
Now, that's Optimism.
