- "Your mother."
- ―Cartridge Unit ("snappy response" cartridge)[src]
Cartridge Unit was a robot who lived in a community of outdated robots who refused to upgrade. This community preferred to live a simpler existence on a little island, free of technology. The speech of Cartridge Unit is merely a playback of selected cassettes, although the selection is always made by Cartridge Unit itself.
It is possible, that Cartridge Unit never actually existed, as his only appearance is in Bender's vision as a result of the Robot 1-X compatibility upgrade. However, he appeared on the Wheel of Robots.
