I found the South Park episode with WoW extremely funny....
"This guy has been logged on continuously since the WoW game started.... "
"You mean...."
"Yes, we're dealing with someone who has.... no life!!"
"How can you kill someone who has no life??"
And Cartman's memorable catchphrase right at the end.... "Prepare to be poned!!"
Also, the "Oh my God.... he's killed Kenny" scene!!
One of the funniest South Park episodes ever.
