Was a fictional character played by the late and great comedian Peter Cook.
Off topic I know .....
Streeb-Greebling was a stereotype of the upper class English twit, described as "narrow-minded" and occasionally a " heartless bastard ".
John Cleese of Monty Python fame described him as one of Cook's range of " men, particularly English men, so trapped by their culture that they never knew how to live ".
The comedy duo of Cook and Dudley Moore featured Streeb-Greebling in their classic review beyond the fringe.
Every time I see a Great Crested Grebe I am reminded of this character.
