When Marty killed the Janitor
I love this movie to death but one thing I've always wondered how the hell did Marty have the strength to pick the Janitor up off his feet by his throat with one hand and slam his head into that metal bar? Marty is a small scrawny guy just seems way to unbelievable that he could do that.
