I've had my fun with rick rolling before. But Rastley and GM Khadarish took it to a new level when Rastley managed to rick roll a GM, all while getting a few gold spammers taken care of. The original screenshot of this was posted on the Customer Service forums, with various CMs and GMs sounding in. Belfaire even comes on to authenticate the conversation.
I really enjoy it when the Blizzard staff interacts with the fan base like this. We've even been lucky enough to get whisked away for some special face time. I think it shows that behind the corporate face they have to put on, they're really just people too – and like a joke now and then. I wouldn't recommend doing this however, since you might catch a GM that doesn't think it's funny – but since it worked in this case, it's golden.
Check out after the break for the full screenshots. Pretty funny stuff.
