"Language Lesson" joke

>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 entirely 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."
