I put a dead frog in his bed, and I'm currently in the process of drinking all of his gatorade.
Tonight, when I get the chance, I'm unplugging his alarm clock.
I told him when I wake up, that the next time he turns off my alarm clock, without even waking me up, he'll be in a world of hurt since he caused me to miss class. I punched him in the stomach.
I am so angry. This has ruined my daily schedule!
