Strangest? I'm not sure I'd think of any of my collections, past or present, as strange. Maybe all the turtle shells I find? But I can't see that as all that strange, either. People find the number of birds I have excessive, but their food source is entirely the grocery store, so perspectives are different.
Now that I'm thinking about it, I guess the collection that's given most people pause is my board game collection. I don't even have all that many board games, but they're prominently displayed in the living room so it catches people's notice.
