In gym class they would make fun of his shaved chest and balls.
As late as 1983, Eddie Murphy was still making jokes about how the first black president is going to be assassinated for being black-- that is, if he could get elected. It may not have been shocking, but it probably would have been heralded as unlikely to have a black president of a single white mother. Interracial relationships were still less common in the 1980s than they are now, IME.
Modify it a little-- Marty doesn’t know how to navigate the reference books, especially not the more technical ones with separate indexes. After having worked with teenagers for several years, I can tell you that today’s Marty is unlikely to know how to deal with a reference book more complex than Encyclopedia Britannica, and Biff won’t have any clue how to use that. Marty will also wonder where the computers are and why the lady isn’t scanning the books and Doc’s library card when they go to check out.
2011 Biff would be wearing Affliction shirts and be a fan of MMA; 1980s Biff wouldn’t be familiar with either. Marty would be more likely to be sporting a patterned hoodie with straight-leg skinny jeans, a bright t-shirt and Chucks or Vans. Not completely out of place, but enough that he stands out. Marty might make an offhand comment about Netflix in response to a “let’s go to the new movie rental store”, or try to find a USB port on the one computer in town so he can insert his flash drive.
Maybe, but look at the stuff they were using on Star Trek in the 1980s. The iPhone has already far surpassed it. I think the combination of technologies- one device to call someone, watch a movie on, check the weather on, and book a flight on, all while it’s plugged into your car- was still something no one was thinking about.
I think a Chevy Volt would be just the ticket.
Let it not be said that no one saw what you did there.
You know where I think Marty might have the biggest shock? If we changed the setting to New York City.
Comparing the streets, parks, subway, and especially Times Square and 42nd Street from 1981 to 2011 will come as an unrecoverable shock.
Perfect! I thought of adding onto this scene, but you did it better than I could.
Marty: … And why do you keep calling me Joe?
Lorraine: well… That’s what it said on your underwear… Joe Boxer.
My Prius can
My daddy said son, the cops are going to see us
If you don’t stop driving that hot rod Prius
But I’d go for a Tesla - rare and expensive also.
