Back to the Future: Part II

Cafe 80's

"Chicken, McFly!'"
~ Griff calls Marty 'chicken'.

When Marty goes to the Cafe 80's, he encountered both old Biff and Griff, who turned out to be Biff's grandson. When Marty, Jr. went inside the Cafe 80's, Griff mistakenly thought that Marty, Jr. had left the Cafe. Griff and his gang of bullies tried to convince Marty, Jr. to join them to a robbery. Not taking "No" for an answer, Griff both abuses and tosses Marty, Jr. around. With Marty, Jr. knocked out, Marty took his place. Marty said "No" to Griff and tries to walk away. Since Griff doesn't take "No" for an answer, he called Marty "Chicken," and tried to hit him with a retractable bat. Marty managed to escape both Griff and the bullies.

The Hoverboard Chase

Marty borrowed a little girl's hoverboard to escape the bullies. After a chase scene, Marty's borrowed hoverboard stopped because the board Marty was using doesn't work on water. Griff then took out his own hoverboard, The Pit Bull. Griff used the Pit Bull and tries to hit Marty with his bat, but in the process, Marty dropped in the water, causing Griff to lose his balance, and he and his gang of bullies crashed into the courthouse.


I was framed!
~ Griff's last words as he is arrested.

What's wrong, McFly? Chicken! (As Marty walks towards the door, he stops when he hears this) (One of Griff's gang makes a clucking noise) (Marty: What did you call me, Griff?) Chicken, McFly! (Marty furiously turns around and throws his cap off his head) (Marty: Nobody calls me..) (Griff raises his baseball bat) (Marty:(nervously)...chicken.)
