Corrected entry: In this episode, robot homosexuals are referred to as "romos". However, in the first episode, it's referred to as "robosexuals", so that would logically mean that it could be cut down to "robos", so why does a robo suddenly mean a robot hobo?
Corrected entry: After Dr. Zoidberg accidentally breaks the bottle in half, he drops the bottom half on the ground. You hear the sound of glass breaking. Yet later he has both halves on the table, and the bottom half is completely whole.
Correction: Considering the self-fixing teacup and saucer shown in "The Cryonic Woman," it's not hard to believe that it was a self-fixing bottle.
If it would fix itself, then the Professor wouldn't need to be worried about Zoidberg touching it.
Correction: "Robosexual" refers to people who have sex with robots (like in the Lucy Liu episode), whereas "romos" are homosexual robots.
