A Bird Case
Riddle: One day you were walking down the street, and you went to your neighbor's house, and you told him to take care of your parrot. And he agreed and said that the parrot will stay in the house for the whole year, so you go back to your house and in the morning, he tells you over the phone that he has hired 4 maids to take care of the bird. After a whole year, you come back; but you find your bird dead. So, you call the police, and you have 4 suspects and only one of them is the one who killed your bird. The first maid said, "I was using the Bathroom", The second maid said, "I was gardening", The third maid said, "I was cooking", and the fourth maid said, "I was cutting wood". So which maid or suspect killed your bird?
Answer: The answer is it is the cook since the other two work outside and there are two inside, so then when the other two come inside and the cook serves them dinner including the first maid, they all fall asleep due to the sleeping medication in the food and because of this, the cook kills the bird.
