I Remember When Mtv Showed Only Videos

Recently, I re-watched the "Walk This Way" collaboration between Run-DMC and Aerosmith. There is a scene in which the rappers and band members are performing on stage. At one point Rev. Run and DMC walk down a flight of stairs, and, if you look closely, both of them are wearing untied shoes! You know how dangerous that is? They could have fallen down the stairs and both their shoes might have fallen off!
