I have. Ive [SUP][/SUP]accidentally given Beau a zodiac dog (which he replaced with a sea bass) and Bluebear an afternoon teaset thinking it was a laptop.
I can't say I have... I've only ever given my villagers unorderables on purpose and it's usually Ankha just getting spare/repeated pieces of the golden set.
I didn't realize Sloppy Series was unorderable, let alone sought after, so I gave the two pieces I had to my neighbors because it didn't fit my decor. Didn't realize I could have been raking in the millions until one of my friends complained about how much he paid for the bed.
I somehow got a Gorgeous Table, and I really wanted to give it to Colton for his birthday, but I accidentally gave it to Olivia because I didn't notice I had picked it.
Not accidentally, that must be a horrible feeling. I do give certain villagers like Skye and sprinkle items from the princess series, and Mitzi a sofa from the Gracie series because it matched her house.
I have. It was when I first started out and I gave the picnic basket to Beau. I didn't realize that the picnic basket was an unorderable item and I meant to give him a different piece of furniture. Now, I usually give my villagers furniture that I want them to place in their house. For example, I like giving the goldfish because the tank looks nice. ^_^
I don't think I remember giving a villager an unorderable at all. I have accidentally sold my caf? uniform before, I want it back and I don't have one yet.
