Mystery and Secrecy Committee

The Mystery and Secrecy Committee is a society in Springfield that meets once a month.

History
They helped to disguise the fact that there was a secret town meeting from the Simpson family. Gary Chalmers complained to Mayor Quimby as he didn't refer to them by name. Disco Stu says that the society is the most fun he has.

Comic Book Guy says their meetings take 8 hours.
