Do they REALLY move mountains??

I had to drive over to the local post office this morning, and, on my way, I read something interesting on the back of the car in front of me. There, in plain block letters on the left side of the trunk lid, with no logo or other contact information, it said: חברה להזזת הרים khevrah k'hazazat harim. The translation: "Company for Moving Mountains"! Really?!? Certainly NOT with that puny, dented little white car that was in front of me! There was more very small writing on the right side, too small for me to read, so, who knows?
