What do you do when you're not home on time? (joke)?

The other night I was invited out for a night with the guys. I told my wife that I would be home by midnight....PROMISE! Well, the hours ped away quickly, and the beer was going down way too easily. At 3:00 am, drunk as a skunk, I arrived home and just as soon as I got in the front door the cuckoo clock in the hall started up and cuckooed 3 times. Quickly I realized that she would probably wake up, so I cuckood another 9 times! I was really proud of my accomplishment! Having such a snappy, witty solution to avoid a possible severe conflict with the wife. The next morning my wife asked me what time I got home. I said "At midnight, like I promised". She didn't seem disturbed at all. "Got away with that one" I thought to my brilliant self. Then she said that we need a new cuckoo clock. When I asked her why, she said, " Well, last night it cuckooed three times, then said 'oh f**k', cuckooed four more times, cleared its' throat, cuckooed another three times, giggled, then cuckooed twice
