Editor's note: The first step to being a great disco dancer is to master the John Travolta strut: just watch the opening credits to Saturday Night Fever and start practicing in your living room. Now that your chest is all puffed out with confidence and the endorphins are flowing, imagine the glittery, mirror-encrusted lights of your favorite club, and crank up the tunes. Last step to Paradise: adorn all your screens in wild Discotheque wallpapers. Now you’re ready to do the funky chicken!
