I often wondered about the origin of the language construct 'myself and some other people did something'. Why use 'myself'? Why not just say 'some other people and I did something'? The 'myself' construct seems very awkward and I find it grating. Sounds like someone trying to sound formal/educated but not grokking grammar...
