I associate "The Krusty Krab" to fake/secondary/tertiary/spam profiles. People I know personally and those I was able to confirm as legitimate profiles doesn't use that or any other fake information (or just leave it empty most of the time). I only see such fake information in accounts used to advertise their business in someone else's threads.

Culture / group related maybe? I have barely any friends on Facebook with real work details - a lot of them are made up. Especially doctors like to keep their profession (and real names) private.
