Yeah, you can say that about every episode but this time the Griffins and co. are playing the characters. What makes this must-see is Quagmire as C3PO, Chris as Luke and Herbert as Obi wan Kenobi. That has the potential to be the sickest and funniest thing in television history.
The Wacky Races couch gag is one of my favorite ones of the past few years. Burns as Dick Dastardly had me rolling! The rest of the episode was another standard Grandpa backstory. And really, those have been done to death at this point.
