Fender's Last Roommate

I always wondered who exactly Fender's last roommate was. @.@ And one night, while listening to 'Reasons to be Miserable', I came up with the answer.

Fender: "Okay, stop me if you heard this one. A tin woodsman, a walkman, and a mail man are all in the same bar --"
Marvin: "Oh give it up. I know you're only trying to cheer me up 'cos I'm depressing you." *SIGH*

On second thought, maybe Fender pushed him out the window.

(That's the BBC version of Marvin, btw, cause the new lil white one wouldn've be able to fit his big head through the portal. O.o *nods wisely*)
