As bad is in one episode when they go to put a video on. In 1988/9 they could surely have at least extrapolated as far as assuming videos would be on something like a CD. Instead they stuck with a VHS tape but instead of being square it's actually triangular! So they stuck with the existing technology and made it a ridiculously impractical shape. But as it's a comedy show where they also talk about putting a toupee over the ozone layer I guess we shouldn't take these things too seriously.
