Half the jokes I have would probably breach the member guidelines
Anyway....
A farmer was sitting in a bar one afternoon, getting slowly drunk. A man came over to talk to him.
"You look down" said the man. "Its a beautiful day. How can you be miserable on a day like this?".
The farmer mumbled "some things you just 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 id just got it full when she kicked it over with her left leg."
"Is that all? Its not exactly the end of the world."
"Some things you just 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 just cant explain."
"So what did you do next?"
"I tied her right leg to the post on the right with some rope and carried on milking." And just as the bucket was filling up, she knocked it over with her tail."
"You must of been angry now?"
"Somethings you just cant explain." mumbled the farmer.
"What did you do?"
"I didnt have any rope left, 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."
