We had a lot of VHS tapes that got worn out over time because they got watched so many times. My little brothers watched chitty chitty bang bang so much that the quality of the entire film was noticably worse by the time the tape got accidentally stepped on and destroyed.

Also mysteriously all the sex scenes with the incredibly attractive women in the Pierce Brosnan James bond films were worn out too. I wouldn't know anything about that nor does it have anything to do with why I'm now a masochist whos into women that bite, scratch and even stab me from time to time... No correlation whatsoever.
