Idle of Monty Python (4)
I believe the answer is:
eric
'idle of monty python' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eric that I've seen before include "- the Red, discoverer of Greenland" , "-- Sykes; -- Idle" , "-- Idle; -- Morecambe" , ".... the Red, Norwegian explorer who discovered Greenland in 10th century" , "Blair, perhaps" .)
