That seems a bit arbitrary There are no reliable sources given for the current cultural references The whole point of pop cultural references is that such things don t need to be spelled out It just so happens that the writers of futurama inhabit a more mathematical pop culture where Mobius dick is as common as a chicken crossing the road At any rate I guess fair enough and it s not like most futurama fans wouldn t already know anyway and i m sure you have better things to do with your time cheers
