Don't forget The Rope
In a website I know and I love this trope is called "Leave the camera running" here is the article about it:

examples:
Film
2001: A Space Odyssey. Ooh, I went there.
The driving scenes at the start of Manos: The Hands of Fate, there because the director forgot the opening credits.
Every scene in the French movie Cache. The movie is about someone sending video of the guys apartment to him so we as the viewer are treated to two minute long shots of the characters watching video of an apartment building with people walking past. Other choice shots include three minutes of random kids swimming laps and two characters talking without audible dialog.
The movie Escape 2000 received the MST treatment. The original film begins with governmental Mooks implying residents to "Leave the Bronx!" They said it so many times, however, that alone it's a Leave The Camera Running and with Mike and the Bots riffing it becomes an Overly Long Gag.
The highway scene in Solaris.
The first Star Trek movie had that damn endless bit with the Enterprise flying over V'Ger while the cast stare awestruck at the screen. Obviously supposed to cause oohing and awwing, it generally just causes yawning. Note that in the DVD release they added some CGI sequences that give you a better idea of what V'Ger looks like, but it makes an overly long sequence even longer.
The rave from The Matrix Reloaded.
That, and the accompanying, ahem, extended "touching moment" between Neo and Trinity that was interspersed amid the raving. Some of this editor's classmates described it as "the sex scene that wouldn't end." These are adolescent males talking.)
Once Upon a Time in the West opens with three Mooks chasing away a ticketman at a train station, then waiting there, doing nothing, for most of ten minutes. Say what you will about some of Leone's other scenes, at least they had good music.
