The Farmer

 A farmer is sitting in a bar getting very 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 my
 wife walked in...
 Some things you just can't explain!
