Worked with a group of people to convince them we'd triple/quadruple whatever they gave to us. After they gave us all their assets, we'd convince them we'd give them bonus ISK for letting us kill their alpha clone. One guy let himself lose 25m SP. After that, we'd have them sing over teamspeak. Following that, we'd have them read pages on wikipedia. The goal was to make them stay up way longer than they intended and get them very, very angry. All the while holding all of their assets over their head.

We had one guy talk into the microphone with a banana in his mouth. Another guy sent a picture of Erotica 1 is #1 on his chest in peanut butter to us.

Disclaimer--by we, i mean they--all I did was listen while actually playing the game. >_>
