The most versatile word in the English language
Speaking of the English language:
Monty Python once wrote a good piece about the most versatile word in the English language. There’s a (probably well known) flash animation in the web out there (for example at the site fun.drno.de, to which’s copy the former link refers) that features this. Very entertaining and grammatically instructive at the same time!
(Warning: As it is the so called f-word which is considered the most versatile word in the English language, obviously the reader will find a good deal of possibly offensive language in aforementioned flash animation.)
