Mike's lack of interest in
"Camp Hole" may stem from a reluctance to work with kids, which will probably only fan the flames of those Mike/Spike rumors, but we'll move on!
"I Found This In Your House"
Think of it as a part "Hoarders", part
Saw, part "Antique Roadshow" and part
Funny Games. People would sign up - or more likely be signed up - for the show, and without any advance notice, Mike would arrive at their homes while they were at work or away for the day to poke around the house, looking for something that caught his attention.
The homeowner(s) would arrive at the end of the day and go about their post-work ritual until, perhaps when they were making dinner or getting ready to pay some bills, Mike would emerge from another room holding the object that he had chosen and greet them with "I found this in your house!"
After the reveal, Mike would have a chat with the resident(s), coaxing out some stories about the significance of what he'd found in their house, how they acquired it and maybe how it related to some unfortunate incident in their life and what it represents in relation to their current spiritual well-being. I'm still kind of hashing the details on this part, but the resident would be prevented from leaving the room during this segment. Maybe not
literally restrained. But maybe. I dunno. This might be the kind of thing you have to play by ear.
