It just seems like harmless fun: people filming themselves lipsynching popular songs, and then sending the results to YouTube and Google Video. People have always done stuff like this: probably the fifth film ever made — after an accidential shot of the floor; sex; a cute puppy running around; and someone else filming the filmer — was somebody pretending to play a Scott Joplin song.
And people have been doing it ever since: it’s a Great American Tradition to totally make a fool of yourself on video pretending to perform a song you love. God bless the U.S.A.
Of course, sometimes other people see these videos, and there are unintended consequences.
