The Hitchhikers Guide To The Galaxy: by Douglas Adams
Bender's head staying in Roswell for 1000 years could be playing on Douglas Adams's "The Hitchhikers Guide To The Galaxy" where Marvin the Paranoid Android stays on a planet for a million years before he is found again in the future! Bender comments "I was enjoying it until you guys came along", while Marvin was miserable alone, and equally as miserable when he was finally found again. "The first million years, they were the worst. Then the second million, they were the worst too. It started going downhill from there"
