Nobody's safe in times of need

There was once a farmer who bought a new rooster. FOr the first weeks, everything went well. At dawn, the roster flew up to the roof above its master's bedroom and crowed as loudly as it could. The farmer started work on time and he was very pleased. But when his birthday came round, he invited lots of people to his house. They enjoyed themselves so much that it was nearly dawn before they went to bed. Hardly had they gone to sleep than the rooster woke them all up with ear-splitting cries. The farmer seized the bird by the neck. "If you can't tell the difference between a master who wants his friends to sleep late, you're not much good to me," he cried. And that was the end of the rooster.
