Sensitivity Training Chip

A small implant with a big voice, the Sensitivity Training Chip is wired into Bender's head to civilize him, and it takes the job seriously. Prim, insistent, and utterly unbothered by how unwelcome its lectures are, it nags him toward politeness the moment he tries to be his usual crude, selfish self.

It's a sight gag turned into a character: a device with opinions, delivered by Tress MacNeille in a fussy, schoolmarmish register that clashes gloriously with Bender's gravelly bluster. The joke isn't just that Bender has a conscience now — it's that the conscience is this specific, chipper, unstoppable little scold.
