Worzel's language is easy to speak.
You spell the word but after each letter you add 'Wor', when you come to the end of the word, if the word is three or less letters you add 'Dip' to the end; if the word is longer than four letters, you add 'Zel'.
Ok equates to O-Wor-K-Wor-Dip
Worzel equates to W-Wor-O-Wor-R-Wor-Z-Wor-E-Wor-L-Wor-Zel
As well as playing Worzel, Jon Pertwee also voices the radio announcer updating listeners on the racing news.
