Characters getting killed are sometimes presented as Mortal Kombat fatalities (complete with Sub-Zero appearing to chastise Phelous/punch Phelous in the face).
The Imogen Heap song "Hide and Seek" playingwhen a character gets shot. Taken to ridiculous extremes in the Funny Games video, when Phelous and some of his friends start walking into the room and shooting each other, and the song plays every time one of them gets shot.
And then one of them pulls out a shotgun and shoots it, and the song is played again, only with SEVERAL of them overlaid.
Sometimes, if something really unpleasant happens plot-wise, he'll use a clip of Tina from Skinned Deep yelling "WHYYYYYYYY?!", complete with a goofy polygon with the word "Why?" written on it. This one started with his review of The Deaths of Ian Stone.
Often when there is a Red Shirt character that gets killed, Phelous would go, "And he/she dies."
In Wrong Turn 2 Dead End, which takes place during the filming of a reality show, one main character eats another's granola bar to prove that he doesn't care about her. Phelous mourns the loss of the potential "Granola Bar Alliance" and cracks jokes about it for the rest of the film.
