I quite like the PREMATURE RELEASE button on a toater.
It kind of demonstrates to the bread that I can be CRAZY when I want.
"Yeah, sure, I said I wanted you toasted on setting 5, and yeah, I know you're not there yet, but I'm going to FORCE you to pop up."
I see it more as a "Yes, you ARE the toaster, but actually I don't trust you to do YOUR job properly. I'LL decide when the toast's done, not YOU."
