A farmer was sitting in the neighborhood bar getting hammered. A man came in and asked the
farmer, "Hey, why are you sitting here on this >beautiful day, getting drunk?" 
The farmer shook his head and replied, "Some things you just can't explain." 
"So what happened that's so horrible?" the man asked as he sat down next to the farmer. 
"Well," the farmer said, "today I was sitting by my cow, milking her. Just as I got the bucket
'bout full, she lifted her left leg and kicked over the bucket."
"Okay," said the man, "but that's not so bad." 
"Some things you just can't explain," the farmer replied.

"So what happened then?" the man asked.
The farmer said, "I took her left leg and tied it to the post on the left."
"And then?"
"Well, I sat back down and continued to milk her. Just as I got the bucket 'bout full, she
took her right leg and kicked over the bucket."
Man laughed and said, "Again?"

The farmer replied, "Some things you just can't explain."

"So, what did you do then?" the man asked.
"I took her right leg this time and tied it to the post on the right." 
"And then?"
"Well, I 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."
"Hmmm . . . " the man said and nodded his head.
"Some things you just can't explain," the farmer said.

"So, what did you do?" the man asked.
"Well," the farmer said, "I didn't have anymore 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."
