Kang and Kodos were no doubt the inspiration for Lrrr and his wife Ndnd, rulers of Omicron Persei 8. We'd love to see the four get together to watch reruns of Single Female Lawyer, and then to try to take over the earth. However, a cameo will do fine, since there likely isn't a whole lot of time to have minor characters show up in this episode, and we're already looking for appearances by Disco Stu and Professor Frink.
