A truck driver is driving down the street, and comes to stop at a stop sign. He hears a knock on his door so he rolls down driver's side window. A blond is standing there and she says: "Hi, my name is Heather and you're losing some of your load". He shakes his head and continues on up the street. At the next stop sign the same blond knocks on his door and says: "Hi, my name is Heather and you're losing some of your load". He drives on to the next stop sign. Again the blond knocks on his door. "Hi, my name is Heather and you're losing some of your load". The truck driver speeds up and at the next stop he gets out, runs over to the blond's car, knocks on her door, and tells her: "Hi, my name is Mike, it's winter in Minnesota, and I'm the salt truck".
