A fished up rusty bucket...
Seriously! I was an usher once for a wedding in East Sarbaruta. I had to tell those coming to this one wedding, which I wasn't a guest of but helped my friend who was chaperone to it, while they were with the GM for the explanations and stuff, to tell them it was the right location.
So some of them were fishing and they forgot to get them a gift, and one fished up a rusty bucket saying that they'd give them that as a gift. It can somehow represent their marriage like a rusty bucket.
