What is the best way to get revenge on somebody without hurting them physically?

There is this one dude i hate with a passion and i want to f his sh** up, what should i do. What are some jokes or getbacks yall can think of. i don't want to hurt him phsically but if it came down to a confrontation i guarantee he won't be recognizable afterward.

I have no problem with hurting him financially, mentally, emotionally, or whatever kind of other way yall can think of.

i have always found that a combination of many little annoying things are the most frustrating for your victim and also keep you busy so you dont try things that might get you thrown in jail.
I always liked grabbing junk snail mail / Email and signing him up for as many as i can for a week straight. getting him a subscription to a gay magazine (assuming he isnt gay) may cost you a little but its better to see his embarassment and trying to explain it to friends and family. Know your enemy, I had a person i wanted to get revenge on and knew he was looking for work. I acted like an interested party at places i knew he had applied at and scheuled an interview with him. so not only did he get all dressed up for an interview and go there, but then the place he went to thought he was crazy so didnt call him for a real interview. just take your time and spread it out. good luck and be creative!

DON'T YOU HAVE BETTER THINGS TO DO THAN WASTE YOUR TIME THINKING OF REVENGE!

WHY DON'T YOU BUY HIM FLOWERS!

there's many thing you can do 1# fine a friend who is really good looking, have her run into him, tell her to ask him for his phone number, have her call him and invite him to a local place. Now you and all your friends be there waiting for him. Went he gets there he will be looking for her,so have her Dias him in front of everyone. And you guys be ready to Dias him... Believe me he won't come around you again..In fact he probably avoid you all together..

LET IT GO. Seriously, I tried it and it backfired.

Forget about him. If you can walk away and never think about him, you deny him the satisfaction of getting under your skin. Beautiful!

If that's not enough, itching powder in the underwear always the trick nicely. ;-)

PRANK THEM!! it'll be fun!!!! and entertaining. Try to do the same he did to you (if its true revenge), try something to make it seem like he did something dirty , that usually gets rid of recognition ;)

Let it go my friend. I dont think he is worth it!

Quit blowing smoke, here. If you think you can take him , then walk up and spit in his eye.

tell him your praying he goes to heaven, soon.

Stop this revenge thing while you can. Let go of the hate,It will kill you sooner or later. Cut it loose. Rise above. It's messing up your life if it's the only thing you can think about. He doesn't care if you hate him. Your the only one who caries these feeling's around,not him.Let it go!

Potato in the tailpipe of his car works. It makes the car backfire really loudly (or so i've heard... ;) ) Also if you put a dime in his gas tank, it does no harm to the car but it will make his engine light come on because the car will sense that something is wrong. They have no sensors to detect when something is wrong with the gas tank and that is the last thing they will fix. So, he will go from garage to garage trying to find out why his car's engine light is on. Again, the dime does nothing to the gas tank nor the car but it will agravate him and he will eventually have to remove the entire gas tank (or have it removed), empty it and shake the dime out the other end. I've never actually done that one but i've heard it works great!!!
Hope that helps!

Revenge is mine, sayeth the Lord. Try forgiveness.
