A farmer is sitting in a bar getting drunk. A man comes in and asks the farmer, "Hey, why are you drinking so much?"
Farmer: Some things you just can't explain.
Man: So what could be so horrible?
Farmer: Well, today I was sitting by my cow milking her. Just as I got the bucket about full, she took her left leg and kicked over the bucket and some things you just can't explain.
Man: So what happened then?
Farmer: I took her left leg and tied it to the post on the left, and I sat back down and continued to milk her. Just as I got the bucket about full, she took her right leg and kicked over the bucket. Some things you just can't explain.
Man: So, what did you do then?
Farmer: I took her right leg this time and tied it to the post on the right, and sat back down and began milking her again. Just as I got the bucket about full, the stupid cow knocked over the bucket with her tail... some things you just can't explain.
Man: So, 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... some things you just can't explain!
