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!"
