Interviewer: How much milk do these cows give?
Farmer: Which one?
The Black one or the brown one? Interviewer: Brown one.
Farmer: A couple of litres per day. Interviewer: And the black one? Farmer: A couple of litres per day. Interviewer(naturally a bit flummoxed): I see. What do you give them to eat?
Farmer: Which one? Black or brown?
Interviewer: Black. Farmer: It eats grass.
Interviewer: And the other one? Farmer: Grass.
Interviewer(now annoyed) : Why do you keep asking which one when the answers are the same?!
Farmer: Because the black one’s mine.
Interviewer: Oh, and the brown one? Farmer: It’s also mine. *Facepalm*
