If former Deputy Attorney General Paul McNulty (left) had taken an actual swing at his boss, Attorney General Alberto "The Law Can Suck Me" Gonzalez, he probably would have been sent to that same Lethal Weapon prison they threatened Rumsfeld with. So the titanium-balled McNulty did the next best thing, claiming he had to resign because the government didn't pay him enough to support his children, or in his words due to "the financial realities of putting two kids through college."
This backhanded bitch-slap of a resignation is great on two levels. If you haven't been following the Gonzalez scandal, and decide to take his word that he can't put his kids through college, the resignation is a very clear, "I'm better than this shitty job, fuck off." If, however, you understand that he's pissed, and just not allowed to say anything, you realize that this is him not even trying to put together a believable excuse, and basically just acknowledging, "Yeah, it's what you all suspect."
