Jon and Karyn gave each other a knowing look, they knew what she was reaching for
they heard her say in their heads. "I wish you had breasts like mine, and everyone wanted to grope them." immediately Biff's chest sprang outwards as his shirt became low-cut and he gained a bra, he looked shocked, and angry, they heard Sarah again say "I wish you couldn't harm me"
Biff Stood up and ran out of the cafeteria, that's when Jon had a strange feeling, he really wanted to feel Biff's breasts, he didn't know why, he didn't get that feeling for girls just Biff, The Wish! everyone will want to grope Biff now. great.
