A newly arrived mech on my Sqn in Germany who had no charisma whatsoever was given the name 'Kelvin'....
The Stn Cdr of a certain station Somewhere in England was also known as 'Kelvin' - or more properly, 'Kelvin Rucksack'.
An absolute zero who everyone has had to carry at one time or another....
There was also a Flt Cdr navigator, affectionately known as 'Admiral Zig Zag' - Admiral because he once did an exchnage tour at BRNC as whatever the fish heads call a flight commander and Zig Zag for his navigational skill. As one pilot once put it, after yet another heading change to regain track (long before the days of FMS or AP NAV mode), "Doesn't he know a number smaller than twenty?".
