Seriously though, I quite liked that tune, especially the singer's voice and the chorus melody. Stylistically the tune reminds me of something else, (as most things do) but I can't quite place my finger on it.
It reminds me of one of my friends in college, who adopted the main line of the chorus as his catchphrase for a short while. I'm unconvinced as to whether it's a way of using humour or irony to distance oneself from the content of the movie (which is admittedly pretty silly in places) or a safe means of allowing oneself to wear the mask of the serial killer so that we can vicariously live out their thrills, or both, or neither.
Either way, it's the people who kill people and make suits from their skins who are the real heroes.
That´s right, the musical! These songs are hilarious. I once found the link somewhere here on Barbelith. You can download those eight songs for free. They get better everytime you hear them. I eshpecially like the Agent Shtarling shinger shinging.
And the chorus on We're Goin' In: "there´s noone here, there´s noone here!"
