Subway Explodes in Laughter

Okay, we've all see those "Flash Mobs" and all of that good stuff, but check out this flash mob of sorts.  Keep in mind this is in Germany, but it still doesn't matter. You have to give these people credit for laughing that long - and that well for that matter.   Before you watch this video be forwarned - It's contagious and you'll end up laughing too!
