I have checked "A Head in the Polls" and I've noticed this:
We all know Bender can move his body, with or without his head on. (Examples: The Series has Landed, I Second that Emotion...) Then, when he sells his body, why don't he bring it back to Planet Express? What a business!!

Surely you think... "Maybe Bender can move his body without his head only in a few distance" That could be true, but when he, Fry and Leela are going to recover the body, Bender's head is very closer to it, and he do nothing...!
Thoughts?
