"What's funny?" Sarah asked, confused.
Biff was about to answer her, when suddenly something happened. Sarah's long blond hair began to shorten down to nearly a buzzcut, the same haircut that Biff had. And at the same time, Biff felt his own hair lengthening until it hit his shoulders, then began to curl. Then he watched as all the make-up disappeared from Sarah's face. Given what had happened so far, he feared that all of that make-up had reappeared on his own face, and he would be correct.
"Babe, you okay?" Sarah asked, uncertain of the odd expression on Biff's face.
Looking around at the neighborhood, Biff hoped that no one else saw him in this getup, not realizing that maybe people might think that dressing that way would be perfectly normal.
