A man decided to take off early from work and go drinking．He stayed there until the bar closed at three in the morning, and he was drunk at that time．After leaving the bar, he returned home on foot．When he entered his house, he didn't want to wake his wife, so he took off his shoes and started tiptoeing(用脚尖走)up the stairs．Halfway up the stairs, he fell down．That wouldn't have been so bad, but he had some empty bottles in his back pockets, and they broke．The broken glass hurt his back terribly．He was so drunk that he didn't know he was hurt．A few minutes later, when he was taking off his clothes, he noticed the blood, so he looked himself over in the mirror．He found his back was hurt terribly．He repaired the damage as best as he could and then he went to bed．The next morning his head was hurting, his back was hurting, and he was trying to think up a good story when his wife came into the bedroom．He told his wife his story．“Well, you really tied one on last night,” she said, “and where did you go?” “I worked late,” he said, “and I stopped for a cup of beer．” “A cup of beer? That's a joke,” she replied, “and you were drunk last night．Where did you go?” “What makes you so sure I got drunk last night?” “Well,” she replied, “my first big clue(线索)was when I got up this morning, I found many Band-Aids(创可贴)on the mirror．”
