If there is one song everyone knows, it has got to be “Build Me Up Buttercup” by The Foundations. It is definitely a favorite.

TJ Smith takes this song to the street, literally, with Highway Sing-A-Long. In Highway Sing-A-Long, Smith rolls down the window in traffic and belts out his favorite songs for the world to hear. He also has the passenger in his car record everyone’s reactions.

Not all reactions are positive, but they sure are funny.

Check out the hilariously, fun video below!

What would you do if you came across Smith in traffic? Would you sing with him or just ignore him?
