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.
