2 years ago my friend shit in a trash bag with a bunch of styrofoam peanuts in it and we dumped lighter fluid,gas and some cans of axe in it,we put it on a neighbors door step at 3 in the morning and I kicked the door so hard that the locked door shot open on the 3rd kick lol.
He came running out seconds later with the half end of a pool stick.He was fucking snapping he hit his mailbox with the pool stick lol.He goes in and comes out with a big ass comforter blanket and throws it on the fire and it didn't do shit but go up in flames,I guess he expected to smother it.So he goes back in and comes back out with what I guess was a bucket of water,He dumps it and it barely did shit lol.He repeats a couple more times and each time it barely does anything and the flames like 4' now lol.So eventually the fire department had to come and put it out.
We watched the whole thing from the train tracks that cover the whole street,it was a perfect view.
We checked out the damage the next morning,he has a awning covering his doorstep and it was melted lol.He was an asshole anyway so I didn't really feel bad for him.My friend also tagged up his car before this.
I guess this could be considered harmless since nobody got hurt.
