Long but nice
This is one I heard about, but it's great so I'll tell it.

Years ago an electrician I knew was ripped off $20,000 by a builder he did some work for. The builder just flat out refused to pay, and due to crazy building laws at the time, the electrician knew there was nothing he could do about it.

Refusing to take the loss on the nose, the electrician proceeded to launch an annual campaign against the builder that lasted until he'd felt he'd equaled his loss. This campaign included:

* Emptying can after can of 'expanding foam' up the exhaust pipe of the builders expensive Jaguar car. The electrician used enough foam to force it up the pipe into the block. When the builder started his car, the block shit it's pants and blew apart. It's reported that certain parts attached to the block flew off with such force they pierced the bonnet on their way skywards.

* For many years, on both Christmas and New Years Eve, the electrician would cruise over to the builders house with his monster F100 ute, attach a chain to the main water meter with the other end attached to the ute and then rip it out. Given that the times were right before long public holidays, the builder would go without water for up to a week during Christmas and New Years.

* Filling the builders letterbox with quickset concrete. The builders letterbox was embedded in a massive brick gate pillar, so each time he had to practically destroy the pillar to repair the letterbox.

* And finally, the electrician would drill a small hole in the builders electronic gate opener and pump it full with sialine solution. Since it was housed in a waterproof box it would fill up nicely, then be completely shorted out and rooted when it was used.
