Proninciation

I heard a discussion on how to pronounce the letter "H".  Some favoured  "haitch" and some "aitch".  I always wince when I hear anyone say haitch.  To my ears it sounds completely wrong.
I remember learning  the following when very small

Harry went to Hampstead
Harry lost his hat.
Harry's mother said to Harry
Harry where's your hat?"
He said "It's hanging on the hatstand in the hall".

One man who had difficulty was the secretary of the Home Office Sports Club.  He announced that "The  'Ome  Office 'Ockey  team travelled from  'Arwich to the  'Ook of  'Olland".

Some people have trouble with the letter  R
I heard one small  boy say
"The wed wubber wing went wolling down the woad"
Ooh!  What a lot of double yous1
