Funny Radio Car insurance Ad?

I heard a hilarious radio ad for car insurance, and it was with a guy singing something like, "I am driving in my car, Hey some is swerving toward me, I guess it's my lucky day, I'll get out of the way!" Then a narrarator says, in real life it happens more like this, "I am driving in my Ca------" and then someone hits him. If anybody knows what this ad is for or where i can find it that would be awesome!!!
