Biden urges justice for Khodor... um... Kovinsky!

In a somber 40-minute address to Moscow State University students that generated more giggles than rounds of applause, Biden tried to bash Russia for putting Khodorkovsky behind bars on what many believe are politically motivated charges.

At least that was the intent.

What came out was one of the more sensitive moments in recent Russia-US relations in which the entire hall seemed ready to help the desperately struggling US vice president pronounce Khodorkovsky's name.

"Over the past few months our administration has spoken out against allegations of misconduct in the trial of... of, uh... the, um... excuse me... Khodor... Kovinsky," said Biden, almost barking out the last word.

But Biden recovered quickly, adding a self-depreciating joke that instantly endeared him to the crowd.

"You can tell I did not do very well in Russian," Biden said sheepishly.
