“Who ordered muon?”, put forward after the discovery of muon (with the already known electron), was the culminating phrase on the flavor problem or the family problem. Muon behaved exactly in the same way in the QED and weak interactions except for their mass difference. This difference in masses is one of the flavor problems.
