The Topic: Nacho Cheese

It's an interesting phenomenon, that every culture, independently, once developing mass production, will stock the refueling stations of their transportation network with an odd semireplica of a snack food from a southern region otherwise relatively unimportant in the scheme of things.

I highly recommend the Altraxian Th'gs'x served at their speedercar regenerators, Vegan Altraburgers available at their hovertrain monopole stations, and Betelguesan UltraNachos, which despite the name are actually a solid form of beer suspended in a time-matrix.

Anyway, the really interesting thing is that these varied products invariably come with a container of an odd substance, a pseudopolymer with nonnewtonian properties, slightly radioactive, and in fact quite unstable on the probability axis. While nearly all sentients enjoy this bizarre food product for its flavor, dipping cohesion, and hallucinatory effects, only on Earth do they try to convince you it's cheese.
