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
