Why (since Calculon is annoying him so much) hasn't the Robot Devil put Calculon's ghost into a bottle prior to the arrival of Fry and Bender? Or sent him off to some ironically torturous place, far from his office?
When Calculon is packing his suitcase, he puts in a stack of headshots - if he plans never to act again, he would not need them. He also has a robe from All My Circuits; was he buried with the robe? (Possibly Bender stole it for him when they were in Hollywood.)
Calculon claims not to know what a 'second take' is, but in That's Lobstertainment, he does numerous retakes for director Harold Zoid (for one scene, as many as 95); and in Bender Should Not Be Allowed On Television, he seems to know what a 'second take' is, stating that he does not do 'second takes'.
The clip of Calculon's death shown on EEIT is briefer than the death seen in The Thief Of Baghead; however, the entertainment show may have edited the footage.
