If you have watched Back to the Future, you would have only spotted this reference if you watch the credits after the movie.
In the movie, Marty McFly travels to 1955 and he crashes the DeLorean into the Peabody’s barn.
Due to the crash, the Peabody family stick their heads out from the barn.
The little boy claims that the Time Machine is a UFO like he has seen in comics.
In the credits, we find out the name of the boy is Sherman. Yes, as in Sherman Peabody.
This is a subtle reference to fellow time travellers, Sherman and his dog Mr Peabody.
