On that Jimmy Fallon-Bruce Springsteen bit mocking New Jersey Gov. Chris Christie last week, Yahoo! News reports (emphasis added):

He said he hadn’t watched the song parody that his hero Bruce Springsteen and Jimmy Fallon threw together (singing “Governor Chris Christie Fort Lee, New Jersey traffic jam” in the place of “tramps like us, baby we were born to run”). But he’d gotten a direct message on Twitter from Fallon assuring him it was all in good fun, and his oldest son told him, “It’s actually kind of cool to have Bruce saying your name.” Christie said he wasn’t angry about it.
