"Here are four kilos of meat," Nasruddin told his wife. "Please make a nice stew! I'm going out now to invite all my friends."
Nasruddin's wife made the stew but it smelled so good that she invited her friends over, and they ate all the stew.
When Nasruddin got home, his wife shouted, "That cat gobbled the meat before I could cook it!"
Nasruddin looked at her suspiciously. He grabbed the cat and put it on the scales.
"Four kilos!" he said. "So, if this is the cat, where's the meat? And if this is the meat, where's the cat?"
