英語笑話:Until They're Free（直到免費爲止）

Deciding to do some back-yard landscaping, my father-in-law went to the brickyard to buy quantity of brick. When he asked the salesclerk about the cost, the man replied. "The more you buy, the cheaper they are."　　"'is that so?" said my father-in-law." Then just keep loading them on my truck until they're free.我岳父打算買些磚來修整一下後院。他到磚廠拉磚，當問到磚價時，售貨員回答說：“買得越多，價格越低。” 　　“真的嗎？”我岳父說，“那麼往我的卡車上猛裝吧，一直裝到免費爲止。”
