One morning last week Mr. Leung turned to his wife and said, “I believe I heard you driving your pigs to market last night, my dear.” Mrs. Leung was surprised, "Why no, dear, I would never do that. It isn't considered ladylike." If you are wondering what Mr. and Mrs. Leung are talking about, drive (one's) pigs to market means to snore. It's a slang.

turn to 转向
believe 相信
ladylike 淑女的
wonder 想知道
snore 打鼾

单看字面，我们是难以猜到“drive (one's) pigs to market” 的意思，因为这不是指“往市场赶猪”，而是“打鼾”的意思。
