Hey, fill a paper bag up with poop, set it on fire on his porch and then punch his doorbell.....he'll stomp it out.....;-)
That reminds me of his dog mine died in the early nineties and I was still picking up dog shit until just a few years ago when his died

I do the spam list email thing to people who low ball me on classified ad items they still seem to collect email info when filling in the email section for porn sites and getting an error message for leaving out the other info without signing up (not sure if I explained that right but I learned the hard way that its true)
I would rake all of the leaves from my side and place them in his yard then stand there and wait for him to say something. I'd count my one tree and show him my one finger (not the middle) then count his four and show him my hand and then say "Go to hell."
I forgot to mention that the guy is usually high as a kite and doesn't communicate well at all. The last time I talked to him (about pushing snow out of his driveway and pushing it under my truck) my portable phone rang and I had a whole conversation with someone else and he didn't even notice
Sounds like this guy is probably going to screw himself over at some point. No need for you to waste your time.
Scare the bejeebers out of him, he'll kick the bucket, you get his wife n kiddies, instant family, just add Bbad......;-)
Put one or more panduit straps on his drive shaft. Someone put a 36" one on mine once (as a joke). It made a hell of a noise and I thought something was broken!
