How do you get even with someone?

someone screws you over big time. one of your best friends. someone you knew for a long time. my question is how do you get revenge? I'm thinking about the whole calling and having pizzas deliver to his house. what would you do? i know I'm sick for wanting to do this.... but its kind of funny.How do you get even with someone?
KILL THEM WITH KINDNESS! Smile, give them flowers, be sweet, hug them, act like they are the best thing on Earth, compliment them, ask where they learned to be so beautiful. It will drive them nuts! Definatly over do the niceness and it will get under their skin! :)How do you get even with someone?
idk, i have to get some help to know what to do with one person that i thought was my friend. well i tried having one of my friends help me but it didn't work.
one time i sent flowers to a person and they thought they had a secret admirer...then i started sending mean notes but it was a pretty good revenge...or u could do taxis
You go be happy and get in shape! Getting even is immature and makes you look weak.
getting back at people isn't always the answer sometimes you just need a open heart to heart chat, try the chat first then if they are this way go with something more evil not just pizza!
act better than them and never look back.
do da pizza thing


or ave a go


but not too cruel
