Nightcrawler: Haha, im already on question 5, and i didnt even study! Everyone else: Lazing around since Nightcrawler is STILL doing the test Miss Circle: Sleeping behind the teacher's desk Baldi: Sitting on the teachers desk, twiddling his thumbs Nightcrawler: Yes! Question 6, and that only took me... Looks at nonexistant watch ... 4 hours. Cloaker: He's so far behind, he thinks he's first... Bad Cop: His eyes are open, his head moves... But his brain has long since departed. Gnarpy: If he got any denser, he'd make lead look light... Bad Cop: Tch, he must have gotten into the gene pool while the lifeguard wasnt looking... Cloaker: Not the brightest lightbulb... Jotaro: Are you kidding me? The lightbulb isnt even screwed in! Gnarpy: The only thing that head seems to be used for is to seperate his ears... Jacket: Guys, cmon, leave him alone. Cloaker: Nnno. He's the kind of stupid that if i left him alone for 5 minutes, he'd set water on fire- Nightcrawler: Alright! Question 6, DONE! Only... 24 more questions to go. Baldi: Sharp as a marble, that one... Miss Circle: Rolling over on her mattress behind the teacher's desk, talking with her eyes closed He shouldnt think too hard... Wouldnt want that poor, overworked braincell to have a panic attack...
