The living room rug was a rug owned by the McFly family in the 1970s. When Marty McFly was eight years old, he set fire to it, resulting in his parents George and Lorraine Baines McFly coming down hard on him.

When Marty spoke to Lorraine in 1955, he recommended that if she and George had kids, that they go easy on their child, who would end up to be Marty.
