A farmer is sitting in the neighborhood bar getting stewed. A man comes in and asks the farmer, "Hey, why are you sitting here on this beautiful day getting drunk?"
Farmer: "Some things you just can't explain."
Man: "So what happened that is so horrible?"
Farmer: "Well if you must know, today I was sitting by my cow milking her. Just as I go the bucket about full, she took her left leg and kicked it over."
Man: "That's not so bad, what's the big deal?"
Farmer: "Some things you just can't explain."
Man: "So then what happened?"
Farmer: "I took her left leg and tied it to the post on the left with some rope. Then I sat down and continued to milk her. Just as I got the bucket about full she took her right leg and kicked it over.
Man: "Again? So, what did you do then?"
Farmer: "I took her right leg and tied it to the post on the right."
Man: "And then what?"
Farmer: "I sat back down and continued to milk her, and just as I got the bucket just about full, the stupid cow knocks over the bucket with her tail.
Man: "Wow, you must have been pretty upset!"
Farmer: "Some things you just can't explain."
Man: "So then what did you do?"
Farmer: "Well I didn't have any more rope, so I took off my belt and tied her tail to the rafter. In that moment, my pants fell down and my wife walked in.
