Is Lambda Lambda Lambda a real fraternity?

I'm curious to know, is Lambda Lambda Lambda a legitimate fraternity that exists in the real world, or is it simply a fictional organization mentioned in popular culture? If it is a real fraternity, could you provide some background information on its history, values, and any notable achievements or contributions it has made to society? Additionally, are there any specific requirements or qualifications that one must meet in order to become a member of Lambda Lambda Lambda?
