A few years ago we used te have this recurring gig every half year at one of the bars when te local carnival was in town.
One of our craziest gig was there and things got a 'little' out of control.
(note: we play thrash, it's a pretty small bar, it's our hometown, the place was crammed, 95% of the people know us and had been drinking since noon

)
First song starts and everyone goes crazy, halfway through someone goes flying though the big window and onto the sidewalk, he hit the pavement and jumped right back up, everyone thought it was awesome.
Barkeep says 'oh poopie, well, those things happen'
Gig continues...we don't even get halfway through the set and someone crowdsurfing get banged down on the pinballmachine and one of the legs buckles. Song is over, machine gets moved, gig goes on.
about 3/4 into the set police shows up outside the door, because there was no more glass in the window neighbours started complaining about the noise.
So the cops are looking at us through the broken window and afther the song we were playing is finished the barkeep comes to the front and the following conversation took place:
"Could you guys turn down a bit, the cops are here"
respons "...no"
And we cranked up our amps one more notch as the cops where looking and started our next song, crowd LOVED it

(barkeep told the cops she would put a piece of wood in the window, and since it was the local carnival the cops just let it be)
Eventually the last song comes up, witch is always our drunken-singalong-song, and since eveyone knows us, eveyone wants to jump onstage...the stage did not like it to say the least
The end total was: One big broken window, One pinballmachine, One warning from the cops, A couple broken planks from the stage, and a bunch of broken beerglasses and bottles on the floor...
Besides al the it was a pretty normal night
