HBO’s “Game of Thrones” is known for bringing out powerful emotions in its viewers, and a new video parody touches on that aspect of the drama in musical form.

Not Literally Productions, a parody and sketch comedy group, changed Goyte’s hit “Somebody That I Used to Know” to “A Character I Used to Know,” expressing their frustrations at watching the first season of the series and seeing the many characters George R.R. Martin, the author of the books the series is based on, killed off.

“But you didn’t have to kill them off,” the group croons. “George R.R. Martin, why are you such a sadistic bastard?”

Playing the parts of characters in the show as well as two women watching “Game of Thrones” for the first time, Ginny DiGuiseppi and Dana Ritterbusch mourn the deaths of Khal Drogo, King Robert Baratheon and, most surprisingly, Ned Stark.

The HBO drama has spawned innumerable musicvideos, mash-ups and parodies. Fans often forge strong bonds with the fictional characters, and season 3’s “Red Wedding” (“The Rains of Castamere”), in which several beloved characters were killed, created a social media firestorm of outraged and saddened fans and a trend of reaction videos to the gory deaths.

Not Literally Productions raised $4,030 on Indiegogo to fund the parody and has produced similar parodies of “Harry Potter,” “Doctor Who” and “The Hunger Games.”
