Little Johnny was in class again.Teacher asked everyone "Can anyone
   tell me a sentence
   with the word definitely in it?" Meg puts up her hand."The sky is
   definitely blue." "Thats
   not bad,Meg," says the teacher, "but the sky can be grey or red."
   Young Sally tried :"The
   grass is definitely green." "Good try Sally,but grass can be yellow or
   brown too!"
   Suddenly Little Johnny's hand shoots up."Miss Brown does a fart have
   lumps?" The
   teacher was horrified."No of course not Johnny! What are you talking
   about?" So Johnny
   says,"Well then Miss brown, I've definitely shit my pants!"
