Little Johnny

Little Johnny is sitting in class again and the teacher explains the definition of "definitely". She then asks the class to use "definitely" in a sentence.

A little girl raises her hand and says, "The sky is definitely blue!" The teacher says that she is wrong in that when the clouds come over the sky is not blue.

Teacher, "Anyone else?"

Another little girl raises her hand and says, "Teacher, the grass is definitely green!"

"I'm sorry but in winter the grass turns brown, so the grass is not definitely green. Anyone else?"

Little Johnny raises his hand and and asks, "When you break wind does it have a lump in it?"

Teacher, "No."

Johnny, "Well then I have definitely sh**!"
