Dirty Johnny is sitting in class when his teacher says, “Alright class. Today we are going to use the word ‘definitely’ in a sentence.” She turns to one of her students. “Roberta, let’s begin with you.”

“Umm,” Roberta stumbled, “The sky is definitely blue.”

The teacher says, “Now Roberta, it’s dark at night and at night the sky is black and grey, so the sky is definitely not blue. Edward, why don’t you give it a try?”

He says, “The grass is definitely green.”

“Now now,” the teacher corrected. “I’m sorry, Edward. Sometimes the grass is dead and it's brown. The grass definitely isn’t green.”

Dirty Johnny stands up in the back and says, “Yo teach, is it all right if I ask a question first?”

She says, “Go ahead, John.”

“When you break wind, does it ever have lumps in it?”

She says, “Heavens no.”

Johnny says, “Then I definitely crapped my pants!”
