A man is asking a farmer about his two cows.
Man:
About how much milk do you get from them in a day?
Farmer:
Which one, the brown one or the black one?
Man:
The brown one.
Farmer:
About a half gallon a day.
Man:
And the black one?
Farmer:
About a half gallon a day.
Man (looking puzzled):
Ok..
what do you feed them?
Farmer:
Which one?
Man:
The brown one.
Farmer:
She eats grass.
Man:
And the black one?
Farmer:
She eats grass, too.
Man (becoming annoyed):
Why do you keep asking me to specify which cow when the answers are the same?
Farmer:
Because the brown cow is mine.
Man:
Oh, and the black one?
Farmer:
It’s mine, too.
