Emmett walked calmly into the computer lab, carrying his chain saw. People stared and asked why he had it. He placed it calmly next to his seat and said mysteriously, "Just in case…."
After a while, people turned to their computers and turned them on. Before doing so, Emmett brought some food out of his pocket and performed a small ritual sacrifice to the computer before turning it on. He then logged on, waited a second, and screamed, "Oh my gosh! THEY'VE FOUND ME!!!!!!!" and scurried underneath his desk. After a moment, he climbed back into his seat and tried to look as normal as possible. A few people stared but he ignored them. After a few moments of typing normally, Emmett screeched, "You will all perish in flames!!!!" and continued to type.
After a while, when nobody was watching him, Emmett took his disk out of the computer and hid it. He then took out a bottle of Elmer's glue and dribbled it around the disk opening. He sighed heavily and prodded the woman next to him. When she looked around in annoyance, he pointed at it and said loudly, "My computer ate my disk! See, it's drooling!" She stared at it for a moment, and then shook her head and went back to typing.
Emmett then took out a small Styrofoam box out of his bag and opened it. He took a piece of dry ice out of it and quickly placed it behind his computer. When it started to steam, he shrieked and jumped back from the computer, yelling, "The computer is smoking! Help! It's going to EXPLODE!!!"
The lab supervisor rushed over and examined the computer. Finding nothing, he put Emmett on a new computer.
Emmett brought up a document and began to type furiously, pausing every now and then to stare evilly at the person next to him. The man looked at him uneasily and scooted his chair away.
Emmett pulled a straw out of his pocket and put it in his mouth. He put his hands in his pockets and began to type by hitting the keys with the straw. The man next to him gathered up his things and left, but not before informing the lab supervisor of what Emmett was doing.
Seeing the supervisor heading towards him, Emmett smiled and looked casually at his other neighbor's computer, stared at it for a moment, and burst out laughing. "You did that?" he gasped, and grabbed his bag and left, still howling with laughter.
