Big Trouble

The next day at school, April was madder than ever. She must of eavesdropped on me and my friends conversation.
"Ha, your mom persuaded Carn to give you private lessons, I mean, Carns never done that to me!" April pouted.
I made my way toward science and sat down next to Hannah once I finally opened the jammed door.
"class, we are going to learn about energy input, and output, when I look at this pencil, it is sitting, and energy is not doing anything. This is called potential energy, when I pick it up, it is kinetic."
"boorringg" said Hannah yawning
"the things she talks about would rather make me want to eat my own puke than listen to her"
"and when I set it down, that is kinetic energy to!" the teacher continued
"Is shutting your mouth kinetic energy?' shouted Hannah, Everyone in the class was laughing their heads off, and putting their knuckles in their mouths so as not to be heard, but it was to late. Ms.Clitch was outraged.
"HANNAH, TORY..........out in the hall NOW!"
"But, I didn't do anything!" I said pleading for mercy
"your sitting next to her, you must have encouraged it, I saw you guys talking to!" She snapped
"But I didn't-"
"Ill believe that when pigs fly!" She retorted
"LOOK, A PIG!" said Hannah in my defence, pointing out the window
