Why Hasn't Anyone Made a Parody of the Song "Closing Time" with "Columbine"?

Interesting article from a few years ago on Slate about the minds of the Columbine killers.  Most of us assume it was an extreme case of the ol' "bullied misfits vs. the jocks", but it turns out Harris was propelled by an air of superiority:

It rages on for page after page and is repeated in his journal and in the videos he and Klebold made. But Fuselier recognized a far more revealing emotion bursting through, both fueling and overshadowing the hate. What the boy was really expressing was contempt. 

He is disgusted with the morons around him. These are not the rantings of an angry young man, picked on by jocks until he's not going to take it anymore. These are the rantings of someone with a messianic-grade superiority complex, out to punish the entire human race for its appalling inferiority. It may look like hate, but "It's more about demeaning other people," says Hare.

And was in fact an actual psychopath:

Harris' pattern of grandiosity, glibness, contempt, lack of empathy, and superiority read like the bullet points on Hare's Psychopathy Checklist and convinced Fuselier and the other leading psychiatrists close to the case that Harris was a psychopath.

It begins to explain Harris' unbelievably callous behavior: his ability to shoot his classmates, then stop to taunt them while they writhed in pain, then finish them off. Because psychopaths are guided by such a different thought process than non-psychopathic humans, we tend to find their behavior inexplicable. But they're actually much easier to predict than the rest of us once you understand them. Psychopaths follow much stricter behavior patterns than the rest of us because they are unfettered by conscience, living solely for their own aggrandizement. (The difference is so striking that Fuselier trains hostage negotiators to identify psychopaths during a standoff, and immediately reverse tactics if they think they're facing one. It's like flipping a switch between two alternate brain-mechanisms.)

Interestingly enough, it looks like Harris/Kliebold were the Lennon/McCartney of the school-killing set, partners who fit as perfect complements to each other:

The diagnosis transformed their understanding of the partnership. Despite earlier reports about Harris and Klebold being equal partners, the psychiatrists now believe firmly that Harris was the mastermind and driving force. The partnership did enable Harris to stray from typical psychopathic behavior in one way. He restrained himself. Usually psychopathic killers crave the stimulation of violence. That is why they are often serial killers—murdering regularly to feed their addiction. But Harris managed to stay (mostly) out of trouble for the year that he and Klebold planned the attack. Ochberg theorizes that the two killers complemented each other. Cool, calculating Harris calmed down Klebold when he got hot-tempered. At the same time, Klebold's fits of rage served as the stimulation Harris needed.
