Heading to Poland for Euro 2012? Well after watching this video, you may want to avoid taking the bus while you're there.

Puffing out mushroom clouds of dirt, this is the kind of video that'll have you choking on your Cheerios. Seriously, it ain't pretty.

A Bialystok bus official is shown hammering away at the seat in question with a peculiar dust-punching device, and the resulting plumes are enough to make you reconsider sitting down in public... ever, really.

There's only one thing for it - when you get home, get those sofa cushions in the washing machine, quick smart. And buy a new hoover. Two, maybe. Failing that... a flamethrower. Yep, that'll do it. Or you could nuke the entire site from orbit - it's the only way to be sure.
