fucking with people in wow was the highlight of all of my gaming.
once when i played alliance we "kidnapped" the flight master from org. then while my buddies drug him down to the bottom of the barrons. I made a thread on the realm forums that said
IF YOU EVER WANT TO SEE YOUR FLIGHT MASTER ALIVE AGAIN YOU WILL BUY THE BEEF JERKEY IN THE AH FOR 10,000 GOLD!
i drew a rope and put a gag in his mouth in mspaint.
keep in mind that the flight master will not re spawn until killed so, noon could fly out of org. They paid it.
We also got two full groups of 40 people together and wouldnt let people in MC/BWL until they would pay for something in the shared AH buying the ma right of passage (we would MC someone with a priest and spam guild info until someone connected to our vent.
Once they finally did i had a voice changer i would use (typical bad guy in movie) act. I told them something like if they buy the beef jerky in the shared AH that was like 10K g it would buy them right of passage for a week.
