A kindergarten teacher one day is trying to explain to her class the definition of the word definitely to them. To make sure the students have a good understanding of the word, she asks them to use it in a sentence. The first student raised his hand and said The sky is definitely blue. The teacher said, Well, that isn't entirely1 correct, because sometimes it's gray and cloudy.
Another student says, Grass is definitely green. The teacher again replies If grass doesn't get enough water it turns brown, so that isn't really correct either.
Another student raises his hand and asks the teacher Do farts have lumps? The teacher looked at him and said No...But that isn't really a question you want to ask in class discussion. So the student replies, Then I definitely shit my pants.
