If you thought Keith Letourneau was the world's biggest (and craziest) Ravens fan, wait unti you check out this guy.

In a video posted earlier this week, a Russian man shows his undying support for the Ravens by filming himself in different parts of Moscow, wearing a Joe Flacco jersey and singing various songs. And did we mention it looks like it's freezing?

"Black and purple, B-More representing!" he says at the beginning of the video. "Ball So Hard University!"

The combination of the fake background sound and this guy's off-key singing give this video an extremely high rating on the unintentional comedy scale.
