A Kerryman had a mule whose ears were so long that every time he put him into
the stable the mule grazed his ears on the top of the doorway. So the Kerryman
decided to knock six inches off the wall over the doorway.
'Why don't you take away the ledge under the door?' asked a friend. 'It would
be less dangerous and much less expensive'. 'Look', said the Kerryman, 'it's the
mule's ears that are causing the trouble, not his feet'.
