Do your Homework, Funny Song, Video. I think this video was done a by a teacher. ” Do your homework.  It is worth 10%. ”  That can be true in most classes. ” If you do not do your homework, you are a slacker and a tree sloth! “. That is true in every class .  I really do like this video. It will not be long till all the kids are singing this song! Do your Homework, Funny Song, Video.
