"I don't care what you say, I have a fact to back me up!", said by a person who just looked it up on Google.
"You're wrong, I have three sources!", said by someone who copied and pasted from Wikipedia.
"I'm not wrong, I just have more facts than you.", said by someone who doesn't know what a fact is.
