I really liked "The Thief of Baghead," especially of the film photography jokes. Here's hoping Calculon stays dead but I'm not holding my breath.
Why would he? As previously established, they like their continuity. It wasn't long ago that they established that when a robot "dies" their memories are downloaded into a new, duplicate body. Bender doesn't have that ability, but other robots do. Why wouldn't Calculon just download into a new body and continue acting like usual?
