It might not be a funny memory but one of the best I have, while playing Tibia. It was when Inquisition Quest was implemented, many players gathered to try and do it, players from diffrent guilds that didn't like each other, started to cooperate and try hard to finish this quest. Many died on the way but came straight back to be of help. In the final room many of us were out of supplies, but still we didn't run from that romm, we were doing what we could so all could finish, unfortunetly we couldn't make it, we had to all run out. But we didn't give up, we took new supplies and did the last part again!
