I like the one about the man who was driving in the American desert. His car broke down miles from anywhere, and he tried desperately to work out what was wrong, to no avail, when a black horse galloped right up to his car, came to a screeching stop, looked under the bonnet and said, "It's your distributor!" before running off again.
Sure enough, the horse was right, and the man fixed up the problem and drove off. He stopped at the first little desert town and went into a bar, where he ordered a beer and told everyone his amazing experience. The barman asked him, "What colour was the horse?" Surprised, the driver replied, "Black." The barman said, "You were so lucky. There's a palomino out there who knows nothing about cars."
Heehee DA, very true. There are bumper stickers in Western Australia that say, "Poverty is owning a horse."
There is this joke about an American cowboy who started an unknown 15-year-old horse in the prize annual race for cowboys' horses, and the horse won by 100m! They asked him why he was only racing this outstanding animal at 15 years old, and he said, "I couldn't catch him till last month!"
