My absolute favorite!! No matter how many times I rewatch this show, it never fails to cheer me up or make me laugh. All of them were cast perfectly. I wish the show ran longer, but I think they ended it beautifully. I cried on the last episode. I haven't watched another show that topped this.

When this show first aired I was not a person to watch it but after a few years I decided to give it a shot after some great comments and ABSOLUTELY LOVED IT, I went out and bought the first two seasons and binge watched it, now I own all episodes of this show, so if you are down and out and need a laugh I recommend taking 21 minutes to watch at least one episode, never know it might put that smile back on. This show is "Off the chain mail" Lenonard Hofstadter.
