A husband and wife are sitting on the couch. After a long day at work, they are both just resting and relaxing as they watch a tv show.
Husband: "I am feeling thirsty. Can you please get me some water?"
Wife: "Shall I also get you some pizza as well?"
Husband: "Oh wow! That‘d be great, my mouth is already watering."
Wife: "Good, that means you don't need the water anymore then."
