<human>: Basically, a few weeks ago, I was driving around with a few friends in the middle of the night in a pretty nice neighborhood. I'm going to say this right now, these friends are extremely emotionally unstable and make a lot of ridiculous decisions when they're bored. We drove past a house that had all kinds of decorations, and this house was BIG. The kind of 'big' that makes you think they don't give a shit what happens to their lawn ornaments. Well, among those ornaments was a replica of the statue of David's head sitting on a tree stump. So of course my friend jumped out of the car, grabbed the massive head, and then we brought it back to the house. 

By morning, the head had been decorated with nail polish... Which sort of implied that they weren't planning on giving it back. I didn't think it was that big of a deal, so I went home. About a week later, I was made aware of the existence of this website:

And now I feel completely horrible for having participated in this. If there is a decent way of getting nail polish off of a statue (I'm just assuming using nail polish remover on painted stone won't do much) please help me out, because if we could clean the thing off, I would take the damn head back MYSELF and apologize to them that this even happened. I know that it was childish and stupid, but it wasn't my idea in the first place. I just want to bring it back to them. The worst part is that my friends don't even really give a shit about the fact that the head has been in that family for years. These are very dear friends of mine and have been for years, so I am not going to call the police on them. I just want to make the situation right.

Can you provide a brief overview of the text?
<bot>: My friends stole a statue of a head and vandalized it. I want to give it back, but don't know how to clean the shit off of if. I would appreciate any advice.
