I, (Annoyed Grunt)-Bot/References

Cultural References

 * The episode title is a pun on I, Robot, which is the title of a collection of short stories by Isaac Asimov, as well as a 2004 sci-fi movie loosely based on the stories in the book. Reference is also made to the Three Laws of Robotics (see Trivia below.).
 * References in Robot Rumble:
 * The show itself is a reference to the sci-fi films Robot Jox and Crash and Burn.
 * The show is also a reference to Royal Rumble, the WWE's annual series of pay-per-view TV specials.
 * The show is also a parody of robot combat shows such as Robot Wars and BattleBots.
 * The robot names "Ralph-O-Cop" and "Killhammad Aieee" are references to RoboCop and Muhammad Ali, respectively.
 * Killhammad Aieee bears a strong resemblance to the ED-209 droid in RoboCop.
 * When Chief Knock-A-Homer dispatches Buzzkill with his own circular saw, the announcers say that he's "killing him softly with his saw," referencing the 1970s pop tune "Killing Me Softly with His Song."

Trivia
Lisa's poem contains two equations:
 * Professor Frink says that Killhammad Aieee has been programmed with the Three Laws of Robotics, which are as follows:
 * 1) A robot may not harm a human being or, through inaction, allow a human being to come to harm.
 * 2) A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
 * 3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
 * When Skinner points out that pretending like nothing happened is a cheat, she points out his real name: Armin Tamzarian.

(eq. 1) 4 paws + 1 tail + 9 lives = 1 special cat

(eq. 2) 1 special cat - 9 lives = 1 sad little girl

...........1 special cat = 1 sad little girl + 9 lives

Or, transitively, 4 paws + 1 tail + 9 lives = 1 sad little girl + 9 lives

Subtracting 9 lives from each side means:

4 paws + 1 tail = 1 sad little girl
 * During Homer's final fight with the Killhammad Aiee, right after Homer makes the first shot to the robot's Vlcsnap-2011-10-15-06h06m18s32.png"groin", it picks him up and begins to shake the fake robot shell around him. When the shot shows the inside of the hollowed out robot during this, if you look just above Homer's left arm on the right side of the frame, Maggie bounces up from the floor and is clearly visible for a moment. At no point in the episode is Maggie ever seen entering or exiting the robot, so this odd little "Cameo" goes completely unexplained, as Homer doesn't seem all too worried for her safety when the robot is destroyed moments later.

 * Gil is said to be very poor, yet he is able to purchase a vehicle.
