The jokes make more sense if you watch the episodes leading up to it. This one was very light on MMORPG jokes and more meme cultureitis. The shoutouts of actors we know and love who've become less popular, or ones we love to hate (Starbuck 1.0 was in one), combined with geek icons like Eliza Dushku (who was in Dollhouse with Felicia Day) and Grant Imahara, and it's just a nerdsplosion of joy for some of us.

(I don't play MMORPGs anymore, but thems my peeps. Last week Neal Gaiman!!)
