Replying to Fun day at school

yesterday somebody put this kids shirt in the toilet, so after gym me and my friend saw it and i decided to pee all over it, we go to a private school so it was a white dress shirt, and my piss made it completely yellow. about 45 minutes later somebody came up to me and told me it was a kid at my school named Mike Mallots shirt, this scared the shit out of me because he is insainly hard core, and loves UFC, he does like 100 different martial arts, so he found out that i pissed all over his shirt, so i feared for my life the rest of the day, he came in to lunch with the most annoyed face in the world, i couldnt stop laughing the rest of the day
