Following Sunday night's 20-17 win over the 49ers, the Giants official Twitter account, @Giants, posted a message that may have been a dig at their cross-town rivals. It tweeted:

Some teams are really happy getting to Conference Championship games, but #ImReallyGoodAt winning them! 5-0 all time! #ALLIN

The Jets have spent lots of time talking about their back-to-back trips to the AFC title games in 2009 and 2010, but the Jets, of course, did not win those games, falling to the Colts and Steelers, respectively. With the win on Sunday, the Giants have never lost in an NFC Championship Game and have been able to win two title games in the past four seasons.

The Giants and Jets have been engaging in verbal warfare over the course of the year. Back in May, Giants VP of communications Pat Hanlon responded to Jets coach Rex Ryan, who said the Jets would have beaten the Packers had they made it to the Super Bowl last season, via Twitter: “You gotta be in it to win it” and repeated a Giants motto: “Talk is cheap.”

Hanlon later tweeted: “Tom Coughlin wrote a book, too. It was about a team and an HC that won a Super Bowl.”

Ryan followed up by telling ESPN NewYork.com’s Jane McManus: “My big thing is, I think I can whip Pat. I'm worried about him throwing a BlackBerry at me.”

And then there was curtain-gate, which took place on Christmas Eve. Prior to the Giants-Jets game, the Jets covered up the “visiting” Giants’ Super Bowl logos outside their locker room with curtains -- just like they do before every home game. But the Giants saw it as a sign of disrespect.

They tried to remove the curtains, but a Jets official moved them right back into place. A security guard was put into place to prevent any further tampering.

But following their 29-14 victory over Gang Green, David Diehl, Lawrence Tynes and Zak DeOssie emerged from the locker room to push the curtains aside.

“This is Giants Stadium!” Diehl yelled as he headed back inside to join his teammates. "This is Giants Stadium!”

The game proved to be the turning point in both team’s seasons. The Giants ended up winning their next four games to reach the Super Bowl, while the Jets lost their season finale in Miami and ultimately failed to reach the playoffs after advancing to the AFC Championship game in both 2009 and 2010.

With all the talk from Ryan and the Jets about New York City being a Jets town, reading between the lines it seems that the Giants twitter account may have had some fun at the Jets expense. The twitter account is not run by John Mara or Jerry Reese, so it is not a dig from one of the Giants high-ranking officials.
