Yes it is true, at least according to Sir Patrick.
Sir Patrick Stewart demonstrated how a cow would moo in a British accent. He was on the ‘how to do everything’ podcast when a caller asked how a cow would moo in the various British accents that there are. The caller, a lady, was feeling restricted by her own mooing. She felt that her moos were in the standard Nevada accent of America and hoped to expand her mooing abilities. She asked specifically, ‘how would a person moo in a British accent?’
And Sir Patrick rose to the occasion. Known for his expertise in all things English, Sir Patrick happily explained in great detail the way cows would moo in the British accents. He even went on to demonstrate the regional accents that are usually too complex for many people. Sir Patrick considers himself the best expert in issues pertaining to Britain.
It was not straight forward as many would think. Patrick said that in many countries, a cow’s moo is a moo but not in Britain. He said that Britain is dominated by class, social status and location, thus cows are also prone to moo based on these factors. A cow living in Oxfordshire would moo differently from one in the countryside or semi-industrial town according to Sir Patrick. He grew up in North England and lives in West Oxfordshire.
The cows in his Oxfordshire town would probably go ‘Mooooooouhh’ when he says good morning. That is a conservative moo; there are other moos as demonstrated by the expert in English matters, each determined by issues such as environmental factors, cultural conditioning and political leanings.
The audio transcript gets very funny and entertaining but does not do justice to the hilarious demonstration of bovine dialects; you might want to listen to it yourself. The cockney accent will particularly have you in stitches.
Here is the audio in its entirety.
