I'm on a Russian forum, and someone posted a link to an MP3 that is hilarious.
There's a Russian news announcer who starts off making a report about a sumo bout, and then breaks out in giggles. And then tries to continue -- and he continues to melt down. He moves on to a story about a business consultancy and can't get the laughter out of his system. Oddly, they let him go on for like five minutes -- trying desperately to read the news while cracking up every sentence -- before taking him off.
Even if you don't speak Russian, this is HILARIOUS. I dare you to listen to it without cracking up yourself. (I'm using the fact that it's a sumo report that starts the meltdown as the tenuous connection here.
