A nursery school teacher says to her class,
           "Who can use the word 'definitely' in a sentence?"

            First a little girl says, "The sky is definitely blue."

            The teacher says, "Sorry Amy, but the sky can be grey
            or orange depending on the weather."

            Second a little boy says, "Trees are definitely green."

            "Sorry, but in the autumn many trees are gold or
              brown," said the teacher.

              Third a little boy in the back of the class says, "Does a
               fart have lumps?"

              The teacher looks horrified and says, "Johnny! That's
               disgusting. Of course not!!!"

              "OK... then I DEFINITELY have poop in my pants,"
                said Johnny.
