you don't see this everyday...

I was walking down my street a couple of days ago. It was a snowy morning and the roads were lightly covered with a dusting of snow. As I was walking I heard a sound of wheel sliding on ice. Just as I turned around I saw a car slide through the intersection, hop over the curb, glide across the slide walk and nail the front porch of a house. Yea, that's right I saw a car hit a house. Not something that you see everyday. What is something that you have seen recently that left you with the expression, 'now that is something that you don't see everyday!'
