History Headscratchers / Futurama

* In "Put Your Head On My Shoulder", Amy Wong brings up that her parents promised to buy her a bar if she got all B's and decides she must go by a car because she isntead got all C's. What exactly would've been purchased if she got all A's? An "ar" wouldn't really make any sense.

** Theoretically, the portals should have folded so that the "open" sides faced each other, instead of out into their universes (assuming the tension snapped the portals in place instead of requiring enough space that the Farnsworths could remove their fingers from the edges). Topographically and in practice, the result was virtually (and probably completely) impossible. It's remotely plausible that the universe was inside-out in the box, and that the z-axis was aligned with the external z-axis (which makes sense), but the team obviously fudged the reality around the boxes. If you weatch closely, there's an animation blip around the boxes while they are pulled through each other, which means that even the writing and animation team (including [[ShownTheirWork David X. Cohen]], who wrote and proved a new mathematical theorem just for an episode that [[TakeOurWordForIt didn't actually need the answer shown on-screen]]) wasn't able to figure out how to get it to work.
