Jaws 2 (it's a completely different shark!)

The janitor and Sally wandered back through the school hall together. The janitor was trying to make conversation, but it wasn't working.
"So... you like... stuff?"
"Um... how about them Raiders?"
"Did you know I was in 'Nam?"
Sally just ignored him.
A faint rattling sound was eminating from one of the lockers. Sally ran over to it and opened it.
Nicholas fell to the ground, and opened his eyes.
"Sally!" He cried in a semi-dazed haze as a result of Sally's concerned gaze, checking to see if he had any grazes. He was amazed she had come to find him, and reminded himself he must remember some more lines from Shakespeare's plays to impress her with. Though, that could've just been a passing phase.
"Nicholas! You snore?" Sally said in amusement.
"No!" Nicholas replied stoutly, "I'm just a mouth breather!"
He stood up quickly. "Anyway, who's this guy?" Nicholas asked, pointing an accusing finger at the janitor.
The janitor (whose name was Pierre, by the way) cringed under the power of Nicholas' finger.
"Oh, that's just the janitor." Sally said. "He's harmless, so I told him all about our plot and everything to do with it.... Oops. Hey, Pierre, you aren't the mole are you?"
Pierre cackled maniacally. It sounded like someone throwing stones at an empty water tank, with a hillbilly living inside. "Crack! Crack! Crack! Hey! I'm coming to get youse lousy kids!"
Yeah, kinda like that.
"Yes, I am the mole!" Pierre cried. "And now that I know Sally is trying to get back at Harry, her parents are really in for it! Hahaha!"
He turned and ran down the corridor as fast as he could go.
Nicholas tried to chase after him, but ran out of breath after two steps. Stupid nerds being all weak and pathetic, he thought.
Sally started crying.
Nicholas furrowed his brow, and desperately tried to form a plan.
Slowly, it all came together in his mind. "EUREKA!" He cried, oh so originally.
Sally stopped crying, and looked rather offended. "Well, I had a bath last night, actually."
"No, you silly blonde-slash-MATHS OLYMPIAN! I have a plan!" Nicholas cried, and ran off down the corridor, running out of breath before he even started.
