I try to catch them at a red light, then I pull up beside them and motion for them to roll down their window. Once I get their attention, I say, "You're probably not aware of this, but some idiot put an Obama sticker on your car".
I was driving behind a guy with a sticker that said something like “I hate Rush Limbaugh.” I don’t remember exactly what it said but I do remember I was listening to Rush at the time.
I pulled up next to him at the light, turned up my radio, rolled my window down, gave him a big smile and said, “Hey, you ought to listen to him. He’s on right now. He’s great!” We both laughed.
Deep down I was hoping he’d turn his radio on to listen.
