미국 할아버지와 2년째 이메일교환중인데 저에게 이런메일을 보내주었네요. 몇개는 알겠고, 몇개는 단어는 모두하는데 숨은 뜻을 모르겠네요. 여러분께 도움 요청합니다.  여러분도 한번 테스트해보세요. ============= 1. Those who jump off a bridge in Paris are in Seine. 2. A man's home is his castle, in a manor of speaking. 3. Dijon vu - the same mustard as before. 4. Practice safe eating - always use condiments. 5. Shotgun wedding: A case of wife or death. 6. A man needs a mistress just to break the monogamy. 7. A hangover is the wrath of grapes. 8. Dancing cheek-to-cheek is really a form of floor play. 9. Does the name Pavlov ring a bell? 10.
