I WANT THE TOAST TO POP UP WHEN IT’S DONE

THAT’S REALLY EXPENSIVE. THE POPPING PART IS EASY —THAT’S JUST A SPRING. BUT KNOWING WHEN THE TOAST IS DONE REQUIRES AN OPTICAL SENSOR—NEW TECHNOLOGY.

BUT WHAT ABOUT ALL THOSE OTHER TOASTERS OUT THERE?

OH, THEY USE A TIMER. THEY DON’T REALLY KNOW WHEN THE TOAST IS DONE. IT’S A KLUDGE.

OUR CUSTOMERS DON’T WANT A SUPER-TOASTER. THEY JUST WANT A REGULAR TOASTER, WITH A TIMER, LIKE EVERYONE ELSE.

OH, WELL THAT WON’T BE EXPENSIVE AT ALL. COOL. YEAH, COOL!
