Hehe, I am so talented!
Today I passed by a clothing store, and a large sign at the entrance said: Shout 'Diaoyu Islands belong to China', get a 10% discount; shout 'Japan belongs to China', get a 20% discount. I saw that the shop owner's wife was very pretty, so I casually asked: If I shouted 'The shop owner's wife is mine', what discount would I get? The shop owner's wife said: A broken bone discount.
