The bell ringer at a church dies...

So they put out an ad for a new ringer, and on the first day a guy shows up for the job. He climbs the bell tower, and rather unexpectedly, he runs and jumps and hits the bell with his face. He continues to ring the bell this way for the rest of the time. The priest thinks it's weird but whatever, he lets him do his job. Within a couple of days, though, the man runs and jumps and misses the bell, falling to his death in front of the church. As the crowd gathers, someone asks "Who is that man?"

Someone else replies "I don't know, but his face sure rings a bell."

The next day the man's identical twin shows up to replace him as the bell ringer, and the priest hires him. He climbs to the top, runs, jumps, and misses the bell, falling to his death. Once again, the crowd gathers, and someone asks "Now, who was THAT guy?"

Someone else says "I don't know his name, but he's a dead ringer for his brother."

I was told this joke years ago, and I probably butchered it. The punchline still works, though.
