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" Teacher says, "Sorry, Amy, but the sky can be gray, or white..."
Second little boy..."Trees are definitely green" "Sorry, but in the autumn, the trees are brown,yellow,and red...."
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..."
