 FAIR: The toaster in Kirks house may look like a Dualit, which  doesnt "pop up" when done toasting. When done this model keeps the  toast inside to keep it warm. Theres a manual lever to raise the  toast for removal. But we are several hundred years in the future,  even in Kirks time. How can we know this toaster does not operate  the way we see it in the movie?
