Not606 meet up round Crum's gaff, next door's getting his canister caved in and his van's getting tipped on it's side. Make sure your sister is about though Crum so it's not a complete waste of our time if the geezer next door is out.
And tell your sister to invite all of her mates as well, there could be a few of us and i'll need two at least.
Stick a tattie up his exhaust, shove it up a bit with a stick so he doesn't see it, he won't get 200 yards before his van claps out. Or, put some superglue on his wiper blades, he'll be ****ed next time it rains. Or superglue in his door locks. Or dog **** under his door handles or if you're really sadistic, super glue razor blades to the underside of his handles. As you can tell, i had a miss spent childhood.
. Wait till he gans out and twist his sky dish. Brake fluid his car. Tip of the hotline about lots of weird arab men coming an going. Link his home number to a sex chat line.
Or get a couple of ton of horse **** delivered and tell the delivery people to dump it on his driveway. Pizza deliveries, Taxi's, i'll think of more soon. Me and my mate once painted our neighbours windows with black paint cos he grassed us up for keeping pigeons, the ****. And i can vouch for the brake fluid one, it works a treat, the paint will be bubbling and peeling in no time. Get a small cardboard box and fill it with dog ****, set fire to it and place it on his doorstep, knock on the door and run like hell, find shelter out of site and watch while he stamps on it to put the fire out.
Personally I'd talk with the bloke, if he doesn't respond then fill the **** in, if that doesn't work, fill the **** in again. If all that fails then it's time to up the anti and piss him off with some of the stuff already mentioned on here. Then fill the **** in again for good measure.
Toothpicks in his door locks (house) will cost him a fortune to get a locksmith out and he'll think it's kids.
I'm beginning to suspect Welder's not off welding or whatever in Africa, or wherever the hell he "says" he goes. Just between us (he's not on at the minute), I think he's Mafiosi
