Some scientists created a machine that automatically counts people’s swears when it’s near them, the machine was a big circle with arrows in the middle that would point to the number of swears.
So they bring it to a office building and after a couple days they come back and see the counter is in the 80s.
They then take it to a restaurant and when they come back it’s up around 150.
Finnally the bring it to a daycare center when they come back a couple days later, they can’t find the machine anywhere so they ask a kid hey where did our counter5000 go.
To which the kid replies “oh that, it’s arrows started spinning like a helicopter and it flew away”
Sorry this joke was originally in Russian I tried my best to translate
