Format
For the first several years, the comic consisted of four square panels of dialogue in a two-by-two grid, with a punchline (often a non sequitur, pun, or pop culture reference) in the final panel. In 2005 Stevens abandoned this traditional form and began consistently publishing strips with more panels in slightly more varied configurations. Single panels of the strip are occasionally animated. The comic depicts a world where robots exist alongside humans, with human-robot romantic and sexual relationships commonplace. Although there is some character development and the occasional story arc, most strips are largely self-contained. Recurring themes include annual Halloween strips, featuring characters from the comic in costume.
