"It's me. Biff. I don't how it happened, but ..."
"This is some sort of prank, right? Did Biff put you up to it?"
Biff leaned towards Sarah, who backed off a bit, then ended up getting out of the car. "It's not a prank. I'm Biff."
"Prove it," Sarah said, humoring the clearly confused girl.
Biff got out of the car and walked towards her, about to tell Sarah something that she knew only Biff knew. But before she could, she felt something strange going on with her ... clothes?
She looked down and watched as her muscle shirt shrank and became tighter, turning into a pink baby-T shirt, which hugged her new D-cup breasts. Then her now-baggier jeans shortened in length until they were a pair of denim shorts, then the legs of the shorts merged into one another, turning the denim shorts into a denim miniskirt. Then after that, the back of Biff's sandals rose up four inches, as his shoes became 4-inch heels.
Sarah stared at what had happened to the girl's clothes. She didn't believe the girl when she said she was Biff. Who would? But after seeing this, she started to wonder if this girl really was Biff after all. As unlikely as it seemed.
"I don't believe it," Biff said. "Now I'm even dressed like a girl."
