Max Headroom: The body harvesters Breughel and Mahler from the American series. In a later episode it was revealed that Breughel had to "replace" the old Mahler with a new one:
Edison Carter: Where's your other colleague, Breughel? Breughel: Mr. Mahler? I was short of stock one night, and he made the supreme sacrifice. This new Mahler is on approval.
Merlin (2008): For series 3, Morgana and Morgause held this trope, until the latter was critically wounded and in the next season died.
The New Avengers: In "The Tale of the Big Why", the Avengers find themselves alternatively pursuing or being pursued by a brains-and-brawn pair of thieves who do not even know what the MacGuffin they are trying to steal is: merely that it is extremely valuable in the right hands.
Once A Thief: Murphy and Camier, two cleaners in the TV series who get involved in all manner of strange jobs, including one (ep 19) where they spend much of the episode waiting for a mark whose name is not quite Godot.
Slings and Arrows: They're not villains so much as creepy-but-essentially-neutral set dressing, but the two undertakers in the first season otherwise fit this trope perfectly (including the personality types and manner of speech outlined in the example).
Spaced: The two agents from the first episode of the second series.
Syfy's version of Alice in Wonderland, the psychedelic sci-fi Alice (2009), featured Dr. Dee and Dr. Dum, who were German-accented overweight bald old men in spandex jumpsuits, Creepy Twins torture-technicians specializing in extracting confessions from especially difficult cases. Their eerie narration to each other perfectly matches the page narration above...doesn't it, Dr. Dee? Indeed it does, Dr. Dum.
Several episodes of Blake's 7 feature a couple of Federation functionaries or soldiers acting as a Greek Chorus for the local situation.
