<human>: Dear Reddit,

So, here's the story. For one of my best friends' birthdays back in September I decided to throw a huge kegger to celebrate. A dmall group of us pitched in on the keg amd the guy who picked it up put down the deposit. We invited 400 of our closest friends. (Probably a mistake in hindsight.) We offered free beer around a big bonfire. There were around 50-60 people coming and going throughout the night.

Well, as the night dwindled down, many people left and a small group took the party inside where we eventually passed out. When we woke up the next morning and walked outside to assess the damage, we noticed that our keg had been stolen! We knew of a few shady individuals who had made an appearance at the party and questioned a few of them. But, of course no one knew anything. 

We just decided that we had lost whatever beer was left in the keg, plus the tap that we bought AND my friend's $50 deposit. 

Fast forward to last week, 3 months later. And someone mentions something to my friend about the party. Then this person tells him that he HEARD someone mention how the keg was half-full still and he was going to take it. And after everyone went inside, he took off with it.

My question to you, Reddit, is now that we know the identity of the thief, what measures of revenge should be taken against them? It's a damn shame that we try to host a fun party with FREE beer, and someone is that disrespectful.. Wanted to get some ideas from you guys, since you are more creative than I.

Can you give me a shortened version of the text?
