I don't speak Polish, but I think I can figure out what's going on here. A couple of guys put up fliers for their new "demolition business" around town. Problem is, they don't know anything about demolition and just figured they could make a couple bucks breaking stuff in their spare time. Surprisingly enough, they get a job to take down an old brick wall. So they show up with their only piece of equipment: their mother's Opel.
