Through the peculiarities of YouTube, I came across "The Loving Couple" series.
"The Interrogation"
"Pie For Dinner"
(Embedding is disabled, hence the links)
The oddest thing about watching these (besides, the thought implied by the title that "this isn't going to turn out to be a porn") is that these two actors are in fact real-life husband and wife! That has to count up there as one of the most surprise casting decisions known to man, as its a couple that looks like the classic "too hot for him with her volumptuous figure and massive breasts" with "sleazy trailer trash so skinny that he blows away in the wind" pairing. Turns out to be a real pairing, which makes the couple-fight both look horrifically crappy and unrealistic and yet scarily realistic and disturbing all at the same time.
Other YouTube highlights from the "this isn't going to become porn but it sure looks like it could" genre:
"Dumbass"
"Deciding on a Pizza
"Alexa is a hoeeee"
