Finding Rhubarb

I discovered perhaps the greatest movie ever made, but can't find it.  Join my quest in finding this masterpiece.

----------

Rhubarb was a 1969 British short film written and directed by Eric Sykes, starring Sykes and Harry Secombe. The dialogue consisted entirely of repetitions of the word "rhubarb", all the characters last names were "Rhubarb", and even the license plates on vehicles were "RHU BAR B". A baby "spoke" by holding a sign with the word "Rhubarb" written on it.

Rhubarb is a radio idiom for unintelligible background speech.
