Bender: Well I'm not doing it! It's a robot holiday.
Fry: Really? Which one?
Bender: Only Robannukah, the holiest two weeks on the robot calendar.
Leela: Oh, come on, Bender. Last month it was "Robomadom" and before that "Robonza".
Fry: Man, that one was a blast!
Bender: It wasn't just "a blast". It was a sacred tribute to my ancestral prototypes which happened to take the form of a drinking contest.
