What would today be like if we never heard the famous "Never give up, Never surrender!" So beautifully quoted in Galaxy Quest. What if Tim Allen was killed at "Never give..." To charity?! Yourself a wedgie?! a dog a bone?! We would never know! We would all be like France! Check this out if you don't know what I'm talking about.
How about the famous "4 score and 7 years ago." What if ol Abe got shot after saying "4 Score and 7..." Swans a swimming?! We'd never know. We would've just thought Abe was really into Christmas. Thank goodness John Wilkes Booth didn't pull the trigger then!
Or maybe "All men are created equal." What if all they got out was "All men are..." Awesome?! Brothers? Liars? We would've never known they were created equal. We'd still think that all Steve's were superior beings. Which wouldn't be that terrible.
All I'm saying is if you have something important to say, you better not wait to say it. You might die. So if you make an important discovery, cause a revolution, or realize that I'm awesome. Go ahead and say it. It's not worth changing the course of history by keeping quiet.
