This is really the first episode centered around Adrian Monk and Leland Stottlemeyer's relationship. Obviously, there's plenty of awkward comedy as both do things differently. In my opinion, the alarm clock scene "7:30" vs. "8:00" is just one of those timeless classic moments you get from a great series like Monk. It's a testament to the creativity of the show's writers as well as Stottlemeyer's cleverness in ensuring Monk's happiness.
Now, obviously... things fall apart once we get to the carpet-vacuuming scene, in which Stottlemeyer gives a showstopping tirade: "DO YOU KNOW WHAT YOU ARE? DO YOU KNOW WHAT YOU ARE? YOU ARE THE WORLD'S BEST MARRIAGE COUNSELOR! YOU COULD SAVE EVERY MARRIAGE IN CALIFORNIA, ALL PEOPLE HAVE TO DO IS LIVE WITH YOU FOR TWO DAYS! TWO DAYS! AND THEY'D NEVER COMPLAIN ABOUT THEIR SPOUSE AGAIN!". Also, it's funny when he says he'll call the Vatican and have Trudy nominated for sainthood.
Also, the bit on Karen's video is an interesting story thread, as she does another video in "Mr. Monk Gets Fired" (Season 3, Episode 4), and having the time capsule play into the investigation was clever.
An overall good episode.
