I watched the other day a program, the last few minutes, and on the credits, all names were titled Archbishop, could you explain?

presumably the African desert one?
Archbishop Desmond Tutu - a famous African.
Just a joke.

The North Pole trek had everyone called Sir Ranulph ... after Sir Ranulph Fiennes the polar explorer/adventurer.

Right now I´m watching the one with an 8 wheeled all terrain and now the Q-pod....
Cheers....
