A man comes in and asks him,

Hey, why are you sitting here on this beautiful day getting drunk?

Farmer: Some things you just cant explain.

Man: So what happened thats 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 cant explain.

Man: Ok, but thats 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 cant 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 cant explain.

Man So, what did you do?

Farmer: Well, I didnt 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 cant explain.
