[Handsome Creepy Eel]

Haso received a phone call from his friend Mujo:
"Hey Haso! I've just bought two horses! They're over there in my barn."
"Great!"
"The problem is, I don't know how to tell them apart."
"Maybe you could cut one's ear off."

A few days later, Mujo calls Haso again:
"Hey Haso, your advice worked but then the horses got into a fight and the first horse bit off the other horse's ear. Now they're all the same again."
"Well, maybe you could cut off one's tail."

A few days pass and Mujo is on the phone again:
"The horses got into a fight again and now neither of them has a tail! Help!"
"Hold on, I'll come over."

Haso comes over and inspects the two horses for an hour. Finally, he says:
"Well Mujo, seems you're out of luck. But one of the horses is white and the other is black."
