-hilarious opening crawl. "A long time ago but somehow in the future"
-I noticed Obi-Wan's krayt dragon call was the '04 version.
-"It surrounds us and penetrates us"
-Coach McGuirk in the cantina!
-the 70's cinematography with the blown out lighting from the windows.
-SE Millennium Falcon takeoff but OOT ascent.
-3PO freaking out, "just tell me I don't have to stay in this room"
-"Red October standing by"=awesome
-and yes, that second Airplane reference was golden
It was funny for two reasons, one being it was 100% new and an hour long and two being it's a show based entirely around reference humor and the Star Wars ones have been constant since it came back on the air if not increasing in frequency, the most obvious being the awards ceremony in that episode that aired shortly before ROTS was released.
