In game rickroll...

So me and my mate rickrolled our IT teacher at college and we were just talking about rickrolling.

Anyway i had an idea of like in the 'In-game movie' of the wrath gate event, woulnd't it be funny is when the gates opened, everyone watching suddenly got rickrolled!

*The gates slowy grind open.. a shadowy firgure emerges from the gloom...

NEVER GONNA GIVE YOU UP!*

Then everyone watching got a message from the server saying : You have just been Rickrolled by Blizzard.

Would be funny, Blizz's sense of humor is reknown and i'm sure they'll put in some referance to rickroll.

Feel free to post your ideas on how they could do it :P
