My father was visiting with a friend who was a farrier to a Clydesdale hitch used for advertising purposes (no, not that one, this hitch no longer exists). A man came up and started asking the farrier questions about his job, as he was going about his business. Most of the questions were OK, but finally he asked, 'How much money do you make?'
The farrier set down the Clydesdale's hoof, straightened up, and replied, 'I tell my friends, and the other folks JUST. DON'T. ASK.'
