Angry Cows ©™® 

19 Angry Cows were looking at the sky.
The stupid one said: "It's blue! Why?"
The orange one had on her head a hat
And told the stupid one "You're stupid. You know that?"
The stupid cow said: "Of course I do!"
The others were angry, saying: "We will kill you!"
After they killed the poor stupid cow
They said: "Hey, we're only 18. Wow!"
