"Change me back ... you fucking ... asshole!" Trevor yelled, as he continually punched the old man. When he didn't say anything or make any sort of compliance to his demands, Trevor grabbed the front of his shirt and pulled him to his feet. One thing that Trevor liked about having Biff's body was the fact that he was so much stronger than he used to be. He felt like he could do anything.
"Use your fucking machine and change me back!" Trevor yelled, before hurling the old man across the room.
Unfortunately, he hurled him a little too much and the old man ended up colliding with his machine, breaking it. Sparks flew everywhere and then everything went dark.
"Oh that's just great, you moron," Biff said. "Without that machine, we'll never get back to normal."
