This is a classic bit of what had become a staple of the Dick Van Dyke show, the comedy mystery. It has the team working late into the night/morning. When left alone, Rob sees something he cannot identify and the comedy ensues. Other than an oddly uncharacteristically dry Sally Rogers, it is a very funny episode, especially for season five (their last).
Curiously, when TV Land aired the episode in 2013 the did so minus what is arguably the funniest line. It's still a great episode, but (spoiler alert) at the point when Buddy returns to the office to get something he left, Rob, having just heard the UFO say "uhny uftz" again is certain that Buddy is pranking him. He says "Buddy, you son-of-a-gun, you Uhny Uftz me!" to which Buddy replies the missing line of "Rob, I've done some terrible things in my life, but I've never Uhny Uftz nobody!" The typically great Morey Ansterdam delivery is just perfect, but for reasons I would love to know, TV Land airs a version with the line removed!
