Definitely

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 sometimes be gray, or black."



A second little boy says,"Trees are definitely green."



"Sorry, but in the autumn, the trees are brown."



Then little Johnny from the back of the class stands up and asks, "Does a fart have lumps?"



The teacher looks horrified and says, "Johnny! Of course not!!!"



"OK...then I DEFINITELY shit my pants!"
