Boxcar describes an unnamed Las Vegas casino and a farm engaged in a closed food loop: uneaten casino meals become livestock feed; livestock returns as casino food. When pigs fail to eat the leftovers quickly enough, the food is mechanically agitated using thrusting machines. The practical fix produces an absurd secondary waste stream: a large pile of discarded dildos.
The joke has a recognizably JQD systems shape. A seemingly efficient circular economy develops an obscene remainder because the optimization solves only the variable the operators chose to measure. The story therefore sits comfortably beside Function / Defunction / Refunction, Operational Beauty and the corpus's fascination with ugly logistics hiding underneath polished consumption.
