First of all, Happy birthday Ross, I'm not quite sure if this fits your criteria but its defiantly surreal at the very least.
Back in high school a couple of friends and I suddenly got really interested in Runescape after years of not touching the game. We we're working on some stuff in the computer lab when we all got done we got permission to take some free time to play around, so naturally we all start logging into Runescape...all of us, that is, except for me. I could not for the life of me log in, I was sure that I had entered my information correctly but it kept saying was wrong, so while I'm having my what the hell moment everyone else is logged in, when something peculiar happened, my account was logged into. my friends all sorta went "Hey finally figured out what the problem was eh?" meanwhile I was muttering a flurry of just about every curse word I could think of staring at the log in screen. I look over at my friend like "Does it look like my shits fixed?" when I realize...holy shit my accounts been hacked, and the hacker is online RIGHT NOW. I drop everything and rush to my friends computer and confirm that my account is logged on but it ain't me playing. So we start fucking with him, first acting like we don't know whats going on saying stuff like "Hey man, come to [city] I found some stuff you've been looking for" and the like. After a while we spring a trap asking for high level items my character didn't have, mithril stuff to be exact, we told him that it should be in the bank (I had a password on my in game bank account) so when he said "Sorry I can't my bank is bugged out" I hopped on and said "That's a shame, because my best gear is in there you hacking pile of crap" naturally he starts getting defensive and fires back with stuff like "Dude what are you talking about I'm not a hacker! The banks just bugged out!" to which I said "really now, then what is the name of the person who account you've been talking to then? If you aren't a hacker you should know what his name is!" this goes back and forth for a little before I just drop the hammer and straight up say "You want to know why I know you're a hacker? Because you're talking to the person whose account you stole! I'm going to be real nice and ask that you return the accounts password to what it was before you grabbed it and vanish, or I report you and let Jagex handle this!" (Jagex being the people who handle Runescape) Much to all our surprises he actually did surrender the account back to me and after I got confirmation that the password had been changed back I quickly changed my password and logged in,made sure nothing too valuable was missing and went on my merry way.
