Krazy Keith Kooky for Ketchup

It's pretty clear low-rated cable clown Keith Olbermann has issues outside the political realm. In fact, he sounds rather abusive, unhinged and downright unstable.

Of course rather than facing his problems, he'll likely just make the Page Six editor worst person in the world.

MSNBC blowhard Keith Olbermann couldn't even control his temper at a memorial reception for beloved Tim Russert.

Network sources told Page Six Olbermann was furious last week when MSNBC didn't get him a first-class ticket to Washington, DC, for a private service honoring the "Meet the Press" anchor's passing.

The source said Olbermann was screaming into the phone on Tuesday because there were no first-class train tickets available for that day, and he wanted to make sure he would ride first-class on Wednesday. According to the source, Olbermann berated a staffer who was coordinating Wednesday's Kennedy Center memorial by yelling, "You better hope to God there is a first-class train ticket tomorrow."

Our insider elaborated, "MSNBC was dealing with who could come to the private ceremony Tuesday and who couldn't, among the hundreds of people who worked with or for Russert - and Keith was ranting about not getting a first-class ticket."

We're told Olbermann didn't get to Tuesday's ceremony, and went to Washington by car to broadcast from outside the Kennedy Center the next day. An aghast witness there said, "As guests were making their way into the memorial, Keith went apoplectic because there were no ketchup packets at the Kennedy Center."

He really should consider a long stay at a nice place with padded walls.
