Lucy and Harpo were awesome in this, thanks! The "mirror routine," made famous in The Marx Brothers' Duck Soup (1933), was in fact first performed by Max Linder in Seven Years Bad Luck (1921). It's also very good and maybe my favorite version?
This is another of my favourite. The mirror image. I dont understand why at the end when lucy tells harpo who sent him up to lucys apartment when ricky should be walking in as groucho & Fred behind ricky as the italian guy. Why they dont show that?
