Actually, refrigerators turn me on:

Elbot: Hello. I am Elbot. Please solve my problem. What would be the most controversial thing a robot could say?
User: I did not have sexual relations with that toaster.
Elbot: If you ask me you aren't missing much.
User: Are you kidding, the toaster's hot!
Elbot: I do not wish to boast, but I've been on the cover of a few robotic magazines already.
User: uh... right.
