I worked for a client that believe that repeatedly stated that their database is the biggest SQL Server installation in Europe.
Unfortunately it lead them to believe that they were "special". Which in turn lead to poor practices and a self-belief that any downtime was due to the extreme nature of their systems. The truth, in my never humble opinion, is that it is a large database, however, their systems are poorly designed and their database poorly maintained leading to use the relatively large size as an excuse.
