All in the Family

Here's part of the conversation from my weekly call to check on parents.

Dad: So are you still busy at church?
Me: I preached again on Sunday, and that wraps up our preaching assignments for the summer.
Dad: How do you know what to say?
Me: We look at the church calendar, and then--
Dad: I mean, does someone tell you? Like John's dad, didn't John get all his dad's sermons after his dad died? (Note: My Dad remembers that John comes from four generations of Lutheran pastors!)
Me: Yes, he did--
Dad: Oh, so can't he just use those?
Me: ($#&*^**$)
