Probably a lot of people already did, but im still making this post:

So when you cut spidertron 5000's extremities and the only thing left is his head, you can push him into a sawblade and then the announcers will say:

''Look at that! Spidertron 5000 is inmune to sawblades.'' -Commentatron

''So strong! So handsome!'' -Analysisbot

I've gotten something along the lines of "Spider-tron 5000 cuts saw blades". The dialogue's pretty great.
