This is part of the Frank said feature. You can see more here.
In our neighborhood, you have to parallel park. There is rarely a time to just pull into a spot. Frank had been silly all night and several Frank saids were from that night. This was the last one and we might have been exhausted at that point.
Frank: (in a 70s porn voice) Hey parking spot, I’m going to be inside you.
Me: [Looking at him in bewilderment] What?
Frank: [Cracking up] I’m just a g-d damned gold mine tonight!
