Disaster? Maybe not. Hilarious accident? Oh, most definitely. You know all those cheesy ads, the ones where a hot woman passing by causes fire hydrants to spontaneously erupt and waiters to accidentally pour coffee all over the customer? Well, it's even funnier when it's real. Maybe not for the lady, who probably gets this reaction everywhere, but definitely for the audience.
Watch where you're going: that's the moral to this story. If you really, really have to perve on an unsuspecting woman, at least stop walking. Sure, all this guy ended up with was a face full of steel and a big headache, but it's the embarrassment (not to mention being immortalized online) that'll really haunt him for the rest of his days.
