Good for Cunningham.
It always used to piss me off how many men insisted on being called "Major" years after they went into mufti. If only people realised that the "passed-over-Major" represents one of evolution's major backwaters, and that the British Army is stuffed to the gizzard with such people, who have risen to a point where, short of a brain transplant, they'll stay for life and who couldn't pass a staff exam if the answers were engraved on their eyelids.
And as for "Captain" Mark Phillips, the dim sod who married Princess Anne... on second thoughts, don't get me started!
