Luckily, Buck is there to show them how to rock. Well, that's what he calls it. It seems being frozen for 500 years will screw with your sense of what "rock" is. Considering the story saw him frozen in May of 1987, he should have been asking for Bon Jovi's "Living on a Prayer."
Instead, he seems satisfied with some "rock" that, to our ears, sounds a lot more like the cheesiest synth-disco throwaway ever conceived by man. At least that would explain his dancing, which he explains is called "getting down," but you'll recognize as a particularly embarrassing example of the white-guy shuffle.
Still, the futuristic hottie he's dancing with seems impressed, but hey, she's wearing a space bikini and the stupidest headdress future technology can muster -- her taste obviously leaves something to be desired. After viewing this, I think we can all agree that if this is the future, it can keep its flying cars and space ships, we'll stick with the Internet and the ability to ridicule anything at the speed of light.
Thanks to Matt Fecher for the tip!
