According to German newspaper Schwäbisches Tagblatt, five emergency service vehicles and 22 firemen had to help free the man.
Makes me think the fire services were American, too.
I once called the Environmental Protection Agency because something I couldn't identify was washing into the local river from an unmarked pipe, and a short walk downstream, half the river width was opaque and nearly white. The response wasn't prompt, but it was ridiculous in scope. In the end, it turned out some poor bastards were somehow disposing of a crazy amount of cement mix in a street runoff drain. (I never learned specifics, but I stopped downriver on my way home from work and the plume was visible 2 miles away. The river becomes very broad and shallow downstream, so it looked much worse than it was, I expect.) Hopefully, their fine didn't match the cost of the easily 20+ vehicle response.
