A man comes in and asks him "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's 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. Some things you just can't explain."
Man: "Okay, but that's not so bad."
Man: "So what happened then?"
Farmer: "I took her left leg and tied it to the post on the left."
Man: "And then?"
Farmer: "Well, 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. 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. 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!"
