Rep. Dennis Kucinich (D-Ohio), who dubbed himself "America's most courageous congressman", is suing a congressional cafeteria for $150,000 over an April 2008 lunchtime incident involving an unpitted olive in a sandwich wrap he was eating. The two-time presidential candidate claimed in the suit that he bit into the pit, causing him to sustain dental damages.

The liberal Democrat filed the lawsuit in Washington, D.C Superior Court on Wednesday.

The Daily Beast reports: "According to court papers, Kucinich is demanding $150,000 in damages from Restaurant Associates and three other companies for allegedly causing him “serious and permanent dental and oral injuries requiring multiple surgical and dental procedures” as well as “significant pain, suffering and loss of enjoyment.”'

In his complaint, which was posted on Gawker's website, Kucinich argued: "Said sandwich wrap was unwholesome and unfit for human consumption."

Gawker reported: "Kucinich didn't detail the costs of the dental work, or precisely what "enjoyment" he lost. Or why he's filing a complaint three years after the olive incident."

Kucinich reportedly did not talk about the olive pit incident publicly until five days later. And video from an April 22, 2008 House session shows the congressman speaking without any apparent problems.

ABC News noted, however, that Kucinich does have a "colorful history":

When State of the Union time rolls around, he's known for waiting hours to get an aisle seat and a moment with the president, even George W. Bush, whom he tried to have impeached.

Another example, as part of his 2004 presidential campaign, he invited women to enter a contest to go on a date with him. Eighty women entered the contest that produced one lucky winner.

And, finally, during his 2008 campaign, he only won 2 percent of the vote in the New Hampshire primary, but demanded a recount.

For his part, Kucinich hasn't responded to media inquiries about the lawsuit. When asked about it during an interview with the Daily Beast on Wednesday, Kucinich responded: “This is a private legal matter, and I’m not going to try the case in the media. I can’t do that."
