Reminds me of a news story I linked to off Reddit
I read this story about a year ago and it's still with me.

Guy A is walking home one night from the pub (or maybe a bar ... I think it was a US news story) and sees a rather nice Corvette pulled over by the side of the road. There's a very drunk looking Guy B on the verge being sick. Not knowing quite what to do, Guy A walks up and does a usual 'are you okay' thing.

Guy B is clearly too drunk to answer any questions coherently, and it's getting dark, late and cold. Guy A decides to go through B's jacket to see if he can at least find out where the guy lives, or if he has a cellphone with useful numbers labelled 'Girlfriend' or whatever. No phone, but he does find a wallet, and from the various cards he sees that Guy B lives fairly near by.

In a mixture of kindness, bravado, and not wanting to turn down a chance to take this lovely Corvette for a brief spin, Guy A decides to drive the car and Guy B home. He props up Guy B in the passenger seat in a way that ensures B is not going to slump over on the gearstick, straps himself in, and then drives carefully to B's place, enjoying every moment of this random adventure.

Ten minutes later, he pulls up into B's drive in his fairly nice house and neighbourhood. He takes the car keys out, locates the house key, and drags B into the house and places him gently on the sofa. He replaces the keys on the telephone table, writes a brief note explaining what happened, including his name and address. He sticks the note on the fridge, and leaves, smiling once more at the night's adventures.

As he walks on home, he's surprised to see a cavalcade of police cars charging down the street in approximately the direction of B's house. Noting this on tonight's already long chalkboard of unusual events, he eventually makes it home.

Ten minutes later, there's a very firm knocking at the door. He opens it to see two burly cops holding the note that he wrote just a few minutes ago and asking "Are you this man?" He's asked to accompany them to the police station.

Much explaining later, it turns out that Guy B didn't own the car at all. Guy B was a burglar who had stolen Guy C's wallet and keys earlier in the evening, and made off with the Corvette. Guy B had decided to celebrate this fine acquisition at a nearby bar, gotten far too drunk, tried to drive home, pulled over by the side of the road to throw up, almost passed out, and that's where Guy A enters the story. When he entered guy C's house, C assumed it was the burglar come back to steal more stuff, and hid in his bedroom and called the cops.

So Guy C gets his car back and gets to see the burglar busted. Not sure if Guy A gained anything apart from a story he probably dined out on for years.
