Here is my patented “Leave it With Gunther” method of dealing with unwanted furniture:
Gunther: “Thanks for all your hard work collecting artifacts for the museum. I’d like you to have the complete sloth skeleton.”
Me: “Oh wow that’s a statement. Boy, don’t you think that belongs here? Heh. I’ll tell you what, why don’t you hold on to that until I have room”
Gunther: “Since you found this chicken statue, why don’t I give you a larger example of this particular….”
Me: “A big brown chicken. That’s so great. Can’t have enough chickens! Say, I’m running out of space in my backpack. Let me just take these pumpkin seeds and I’ll pick up that chicken later.”
Gunther: “You’ve been such a good friend to this library and museum, I’d love for you to have this gigantic bear statue.”
Me: takes singing stone and leaves
Of course , once you’ve made the mistake of taking the furniture that’s a different problem. You could put the unwanted items in the middle of some debris and hope they eventually get destroyed. I put a piece of trash in my autograbbers so they function more like a chest- maybe it would hold furniture too?
Of course, there are always bombs.
