If you watch the whole video he does it more “for real” later on, plugging the casing into a power source to simulate a battery discharging… Plus I’ve had some of these PowerCheck batteries, and they were not old, it was like… 2017? So maybe they rebooted it for a short time at some point?? Anywho, if you pressed really hard it did work I think, but also I think I was doing it wrong for a long time as well lol
I think they meant the conjugations, like “cebula, cebuli, cebulą, cebulę, cebulami” etc…
But the part about no word for job is just plain stupid, cause we also have: praca, zatrudnienie, robota, harówa, zapierdol… That’s already five.
