Biff let go of Jon, dropping him to the floor. Then he ran over to the little girl, who was with an elderly woman, presumably her grandmother.
"Grandma?" the girl asked.
"Yes, dear."
"Can I have an ice cream cone?"
"Sure you ..." She never finished her sentence, because at that moment she witnessed a muscular teenage boy grab her grand-daughter. She screamed and began hitting him in the head with her purse.
After Biff picked up the little girl, he immediately kissed her. When she pulled away from him, she yelled "Grandma!"
"We were made for each other," Biff said, smiling. "Let's date."
The girl's grandmother kept hitting him. "Let go of her, you pervert!"
