Hair we go

The increasingly-cerebral PopBitch offers a cyclical theory as a guide to selecting the next Director General of the BBC. It suggests the job has historically rotated between the hirsute and those who are follicularly challenged.

Thus (in PopBitch's assesssment) we have
Alisdair Milne (hairy); Sir Michael Checkland (balding) John Birt (hairy) Greg Dyke (baldy) Mark Byford (hairy) Mark Thompson (baldy)...
PopBitch (not me) thinks this does not bode well for George Entwistle.
