Another anecdote from the collection of J. Maurus.

It was an insult. George Bernard Shaw looked again. Yes, the letter was addressed to a George Bernard Shawm. In a beard-tossing fury,  he roared to his wife that his correspondent could not even spell the name of the world's greatest man. Moreover, fumed GBS, there was no such word as 'shawm.'

Mrs. Shaw, one of the world's most martyred woman, quietly disagreed,  led him to a dictionary and pointed to "shawm... an old-fashioned wind instrument."
