The other cow says, "Why should I? I'm a chicken."
Two more cows are standing not too far from the first two, One turns to the other and says "Moo !" The second looks at the first and says "Damn!, I was just about to say that!"
Yet another two cows are standing not too far from the other four and one turns to the other and says "Baaa !"
"Baaa ??" asks the second "Why did you say Baaa ?"
The first one replies "I'm learning a new language."
