A farmer was sitting in a bar one afternoon, slowly getting drunk. A man came over to talk to him.
"You look down" said the man, "How can you be miserable on a day as good as this?"
The farmer mumbled, "Some things you cant explain"
"Come on, tell me about it," said the man "It might help to talk to someone"
"If you really want to know," said the farmer, "I was sitting in the barn this morning milking my cow and I'd just got the bucket full when she kicked it over with her left leg"
"Is that all? It's not exactly the end of the world!"
"Some things you cant explain," mumbled the farmer
"So what did you do?"
"I took her left leg and tied it to the post on the left with some rope. Then I carried on milking. And just as I got the bucket full again, she kicked it over with her right leg."
"I can see that would be annoying"
The farmer mumbled, "Some things you cant explain."
"So what did you do next?"
"I tied her right leg to the post on the right and carried on milking. And just as the bucket was filling up, she knocked it over with her tail."
"You must have been very angry by now?"
"Some things you just cant explain," mumbled the farmer.
"What did you do?"
"I didnt have any more rope, so I took off my belt and tied her tail to the rafter. At that moment, my pants fell down and my wife walked in. Some things you just cant explain."
