True story. I just got my car out of the body shop for this reason.

I WAS PARKED IN A PARKING LOT AND GOT A BIG DENT IN MY DOOR FROM A RUNAWAY SHOPPING CART. HAVE YOU EVER NOTICED THAT WHEN YOU ARE INSIDE A STORE, YOU CAN'T FIND A SHOPPING CART WITH FOUR GOOD WHEELS... APPARENTLY WHEN THEY FIND THEMSELVES OUTSIDE IN THE FRESH AIR, IT'S LIKE SOMEONE GREASED ALL 4 WHEELS!
