Little Johnny was in class again

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!"
