If you don't know why the early-1980s Buck Rogers in the 25th Century TV series is damn near perfect, then this clip from the episode "Escape from Wedded Bliss" will explain it all to you. Earth is in danger because evil Princess Ardala (wearing the purple spangly lingerie and tiara) has declared that she'll use her superweapon to destroy New Chicago unless Buck agrees to marry her. When she zooms down to meet up with Buck, the Earthies throw a reception for her with "traditional folk dancing" which turns out to be disco skating. As if that weren't enough to make you weep with joy, we see Ardala giving Buck the old predatory eye, while two soldiers behind her sport the Gay Uniforms of the future: all white polyester knit with rainbow armbands. Don't thank me for this clip, thank Buck Rogers exec producer Glen Larson, who also worked on the 1980s Battlestar Galactica.
