Looking passed the absolutely insane answer here, no one has even brought up the whole issue of AC vs DC. Batteries are DC, while your fridge that plugs into your wall running on AC. I know they make DC ones, but it isn’t like they are interchangeable.
I would also encourage people to go to midnight showings of Tommy Wiseau’s ‘The Room’ and watch as people throw handfuls of plastic spoons at the screen. Also fun.
