Singing in the Car

I made this meme today because of an experience I had:
(for those who don't recognize him, that is the numa numa youtube guy)
My day was MADE today as I was cruising down the street and singing my heart out to Bruno Mars - Just the Way You Are. I stopped at a red light and just happened to look at the car behind me and catch an older man belting HIS heart out to the exact same song!!! I could read his lips to the music in my car... I just about died!!! and then... I wondered how I looked to the person in front of me... XD
