this be my favorite movie ever . these be the highlight for me . from groucho sing mr. grover you be just a quack to me to the end of the sing while you sell reprise . virginia obrien have me laugh on the floor the first time i heard rock a bye baby . i just love the way groucho take the big production number and a standard vehicle of the time and and make it signature groucho . you get to smile . i think this movie have some of the best groucho or margaret dumont banter . harpo harp solo be mile ahead of any of his others . it just plain fun and although the tenement symphony clearly be lack musically and you have to love the override pun . the tenement symphony in four flat .
