Lily hated James. And she hated Sirius, too. She was, perhaps, the best student in the third year. And so she was James' favorite person to prank.
James was in love with Lily Evans. She of course, hated him. James was thinking about this as he headed to Transfiguration. He took a seat next to Sirius.
"Hey mate," said James.
"Mornin' Prongs," said Sirius as McGonagall began class. James didn't pay any attention in class, save to the back of a certain girl's head. Lily Evans head, of course. He had snuck into her dormitory{Ten people can apparate in Hogwarts: The Marauders, The Golden Trio- they can't until fifth year-, Lily- she learns in fourth-, Dumbledore & Voldemort} and set fire to her bed. Of course no one could prove it. Only six people in the castle knew what had really happened. Four of them would never tell. One, the esteemed headmaster, had been a prankster himself some 37 odd years ago. And Lily kept her mouth shut because people would say she's biased.
After Transfiguration, the third years had lunch. As they sat eating, the Marauders talked about how close they were to becoming Animagi when a loud crash was heard. They all turned in time to see Frank pin Snape down, his wand in Snape's face as he said through clenched teeth, "Never.. Do.. That.. Again."
