An electric toothbrush can never break: it can only become a toothbrush. You should never see an “Electric Toothbrush Temporarily Out of Order” sign, just “Electric Toothbrush Temporarily Manual.” Sorry for the exercise.
Same goes for those seemingly-useless, single-purpose kitchen devices. You're just probably not in the target audience.
For those of you that are wondering, Mitch Hedburg was a relatively famous stand-up comedian whose special went viral.
In said special was this classic:
“I like an escalator because an escalator can never break; it can only become stairs. There would never be an 'escalator temporarily out of order' sign, only 'escalator temporarily stairs. Sorry for the convenience.’”
RIP indeed.
