Other examples:
Woody Allen's
Zelig and, to a lesser extent,
Bananas; some of
Monty Python's television pieces (
Flying Circus made a mockery of just about anything and everything at one time or another), and
Eric Idle, with
Neil Innes, conceived
The Rutles as part of their
Rutland Weekend Television TV show - the rest is history. Or something. Insert your own Tailwind joke if you wish; I won't go there.
