Ok, so I just watched the news and saw the sign. That thing was soooo rotten at the ground level of the posts, it could have fallen over and killed somebody or even worse.
Here's my theory (oh, right, this is egriz, so not a theory, cause I was f in there man

)
I think he was walking along, minding his business, drunk as hell. Decided to take a break, you know catch his breath, cause breathing is hard to do when you're drunk. So he sees this sign. It looks like a sturdy sign, I mean its GOT 2 posts. Decides to lean up on it and it snaps clean off. Hermy thinks, "Damn, I must be Super Man Tonight. Isht, man, it just snapped like a toothpick." He flexes his arm looks at his minuscule bicep, gives it a kiss, and yells, "Super Man's gun show, One night only!" Then proceeds to rip that half of the sign away from the other half. Once he gets it away, he begins to go all BAM BAM with the thing. He does this for 20 minutes.
Finally, MPD, drives by after they just left the donut shop and see this white kid WAILING on this post. Amped up on sugar, they get giddy and one of them says to the other, "Lets get that Meth Head Cracka."
By the time MPD reaches Hermy, he's no longer super man, HE'S BAM BAM and yelling BAM BAM while swinging that post. MPD yells, "Son, put the post down!" "No, BAM BAM." Was the reply. Finally, after MPD laughed so hard, BAM BAM complied and walked over them. They cuff him and stuff him.
The moral of the story is this:
DON'T TOUCH OTHER PEOPLE'S RICKETY ASS ISHT! You'll get blamed for breaking it even if you just sneeze on it.
