I am a Vol Firefighter in the community where their N American headquarters are located.
Over the years we have had a large number of false alarms at their facility mostly due to burned popcorn.
i.e. short term memory lapses
I'd be in constant peril of burned popcorn, over-running tubs, wood stove getting too hot before dampering down, burned dry pots, etc,. were it not for my whistling teakettle and timer...Although I'm about ready to get a second timer to remind me to set my timer -
