I once recieved a bannanna the villager then said "wow since i've finished using this i figured you could have it!" Lets just say i was pretty amused/uncomfortable about that situation ahhaha
I know this falls under toilets, but a men's urinal. Okay yes, I will put this urinal in my house and whenever a guy friend visits I'll be like, "Oh by the way if you need to pee, USE THIS URINAL right in my living room!" I also get offered a lot of balls.
And I get bootleg fruit. I didn't shake any fruit trees, yet Diana has an apple and will try to con me 600 bells for it.
Once one of my cub villagers gave me a baby bear and I couldn't help thinking that they're giving away their own child. I guess they just weren't ready for parenthood.
I found a skeleton in Bam's closet that he let me have (and Poncho asked for it five minutes later). I also had someone (I think Agnes?) give me a "gently used banana" before.
A lot of things. But i'm gonna say 3 years ago, Ozzie gave me a skeleton while telling me that I saved him in a dream he had. I guess his other buddy couldn't be saved, but he found the body somehow as a gift to me.
