Is the White House Correspondents' Dinner the proper venue to make gay jokes about the husband of a current female member of Congress?

NBC's Jimmy Kimmel certainly thought so as he took a page out of vulgar comedian Bill Maher's playbook claiming Keith Olbermann "has more pink slips than Marcus Bachmann" (video follows with transcribed highlights and commentary):

In the middle of a humorous riff about MSNBC's former Countdown host, Kimmel said, "Keith Olbermann burned more bridges than the Arsonist of Madison County. He has more pink slips than Marcus Bachmann."

This was met with groans from the crowd.

But Kimmel doubled down by saying Marcus Bachmann “plays Cameron on the hit show Modern Family.”

In case you didn’t know, Cameron is one of the gay characters on the program.

Marcus has been a favorite target of HBO's Bill Maher who loves telling sodomy jokes about Congresswoman Michele Bachmann's (R-Minn.) husband.

Just two weeks ago, NBC's Saturday Night Live also took a homosexual jab at Mr. Bachmann in its opening segment.

Honestly, what is it with liberals and gay jokes?
