I have lots of weird stories from MMORPGs like once in Ferentus I was grinding on Werewolves(Back in V1 days) and the highest level Cleric(I knew him well but he didn't say anything) comes up and gives me all his money and his gear and says I quit in shout(I couldn't use the gear but I got a lot of money for it).
another I time I was in D2(Desert 2 PvP area for level 20-50 players) and a few members of Time Thieves thought it would be fun too hunt me down so I PMed a few of my friends from FMJs(They had the highest levels in the server) and they killed the TT members later they PMed me and claimed I had cheated for PMing my friends(I have always hated TT) There was also once near the end of V1 a GM logged on(Which was rare) and gave me free God Gear for finding him first.

And then there is also my RO days(or should I say years?) Once when I had just started I was going to be a Mage and a high level comes over and gives me over 1 million and says "good luck noob" then logs off. Or another time during a WoE on my Sin(Before Trans yay!) a guy though he could sneak up on me and take me out before I noticed so my Rogue buddy was right behind me in invis when the guy got close my buddy jumps out and the guy runs away.
