Nasus, how come Teemo's so evil?

It's because he's not a Yordle Teemo's not a Yordle?! No way. (Nasus gets an Idea) I... Thought you knew. Have you ever known anyone that evil?... Well? If Teemo isn't a Yordle, what is he? You didn't hear this from me but... Deep down, in Riot games headquarters, in a top secret lab! A Mad Designer, by the name of 'Ezreal' was thinking up champions! Do tell! By combining, an evil mega imp from hell, and a sweet badger, thus creating, SATAN!
