When we first moved here I went to rent a movie and really confused the person at the counter because I had the same address and phone number as the former pastor but a different name.
We just had a guest preacher who married a former pastor's daughter of our church. He called the night before church to tell us he was here. He enjoyed dialing the phone number because it was his wife's phone number when they were sweethearts (I think about 25 years ago!).
I'm sure most of our members have the pastor's phone number memorized because it has always been the same. That fact makes the telemarketers that call for a former pastor worth it.
