Little Johnny let out a loud fart in the middle of class, causing his teacher to become so angry that she sent him out into the hallway.
Sitting alone outside the door, Johnny couldn't contain his laughter. The school principal happened to be walking by and saw the boy giggling to himself.
"Little Johnny," the principal asked, "why are you out here in the hallway laughing?"
"I got thrown out for farting in class," Johnny explained.
The principal was confused. "Well, if you were just punished, why do you find that so funny?"
A wide grin spread across Johnny's face. "Because all those idiots are still stuck in there smelling it, and I'm out here getting all the fresh air!"
