Ok here's my idea. Whenever there is a war declared. The President/Prime Minister/Dictator/King/Whatever you have, has to go and fight in the front lines of the war. During this period of time the Vice President/Whatever will take over the duties of leader of the nation. I believe that this would force our authorities to give diplomacy much more of a chance instead of letting their military might do the talking.

You just finish your dirty business in the bathroom. Imagine if the toilet seat then thanked you. The toilet would have a built in speaker at the base and many pre-recorded messages such as. "Thank you have a nice day" or "have you been working out" or "I really enjoy the time we spend together". I think it would really give people a pick me up.
