A man carrying a jug of milk stopped Mulla in the street. "Mulla, I need your advice. I don't drink alcohol, but every morning when I wake up, I feel incredibly drunk and dizzy." Mulla looked at the milk jug and asked, "What did you have to drink last night before bed?" "Milk." "Ah, just as I suspected," Mulla said confidently. "Here is what happens: You drink the milk and go to sleep. You toss and turn all night. All that shaking churns the milk into butter. The butter ferments into cheese. The cheese breaks down into fat. The fat turns into sugar, and the sugar ferments into alcohol. When you wake up, your stomach is full of booze! That's why you feel drunk." The man was amazed. "What should I do?!" Mulla grabbed the jug out of his hands. "It's simple. Stop drinking milk. I'll dispose of this for you." And Mulla walked away with the free milk.
