Washington, D.C., has been aflutter with the incoming crop of new Congress members, the largest freshman class since 1992.

Washington, D.C., has been aflutter with the incoming crop of new Congress members, the largest freshman class since 1992.

"It's like the first day of school up on Capitol Hill," said Norah O'Donnell on "Morning Joe."

It's the same kind of excitement that fills college campuses every fall as upperclassmen peruse the freshly stocked pond of freshman meat.

Tea Party reformer who ran on smaller government - I'll screw you in the first week.

But it's not all about the newbies. In fact, it's really 90 percent oldbies in Washington. And there's no olderbie than Arizona Sen. John McCain - senior senator, I should say, because he's senior even by Arizona standards, which is saying something.

Fun fact: McCain is the only sitting senator who also served in the Roman Senate. Julius Caesar, that's not change we can believe in.

McCain stands now as less of a paragon of straight-talk independence for new members to admire and more as an object lesson in just how freaking mad people get when they don't get their way.

It was a trait on display following the recent historic repeal of "don't ask, don't tell," the ban on gays openly serving in the military.

"This vote will probably pass today in a lame-duck session, and there'll be high-fives all over the liberal bastions of America," McCain said, "in the elite schools that bar military recruiters and the salons of Georgetown."

Liberal bastions?! Salons of Georgetown?! What decade are you living in?! You know the reason Katherine Graham doesn't invite you to hors d'oeuvres with the French ambassador anymore is because she died 10 years ago, right?

Not to put too fine a point on it, but liberal bastions don't generally high-five. We harrumph approvingly.

The most galling aspect of the senator's reaction isn't his bizarre class resentment - seriously, people who live in 10 homes shouldn't throw stones - but his dire predictions regarding the insidious effects of granting American citizens the full right to fight for their country.

"Today is a very sad day," McCain said. "The commandant of the U.S. Marine Corp said, 'When your life hangs on the line, you don't want any distractions. Mistakes, inattention and distractions cost Marines lives. I don't want to permit that opportunity to happen and I'll tell you why - go up to Bethesda Naval Hospital, there are Marines up there with no legs.'"

Here's the thing - some of them are gay. And maybe it'd be nice that in exchange for those limbs, they could be visited by their significant others without having to refer to them as "a college friend."

McCain's old man crankiness has gone off the charts, from a man of wisdom to full-blown "Gran Torino."

So, seeing how easy it is to annoy McCain, I'm making it my mission to do so. How will we do it? Maybe a practical joke, given his aversion to certain lifestyles.

I think I'll go on Foursquare and check him in as the mayor of the Bear Elegance Gentlemen's Club.
