A farmer is sitting in the neighborhood bar getting soused. A
man comes in and asks the farmer, "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 is so horrible?

Farmer: Well if you must know, today I was sitting by my cow
milking her. Just as I go the bucket about full, she took her
left leg and kicked it over.

Man: That's not so bad, what's the big deal?

Farmer: Some things you just can't explain.

Man: So then what happened.

Farmer: I took her left leg and tied it to the post on the left
with some rope. Then I sat down and continued to milk her.
Just as I got the bucket about full she took her right leg and
kicked it over.

Man: Again?

Farmer: Something's ya just can't explain.

Man: So, what did you do then?

Farmer: I took her right leg and tied it to the post on the
right.

Man: So then what did you do?

Farmer: I sat back down and continued to milk her, and just as I
got the bucket just about full, the stupid cow knocks over the
bucket with her tail.

Man: Wow you must have been pretty upset!

Farmer: Some things you just can't explain.

Man: So then 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.
