All the above suggestions are obviously a lot more sensible and moral but if revenge (but only a little bit) is what you want then tape a piece of raw fish to the underside of his car seat, or somewhere similary difficult to reach. After a few weeks (especially if the weather is warm) the smell will be unbearable and very difficult to find where it's coming from!

Here's a peach that was passed to me by a male friend: Ok, so you've finally seen the light and decided to leave that scum bag boyfriend of yours. Unfortunately, leaving means you are abandoning your shared accommodation. You want to leave with your dignity by being the adult in the situation ( i.e. not burn his CD collection and give all his cloths to the homeless) but you just can't bear that he's getting off so easily either. Hit him with this subtitle but effective revenge tactic: Batteries. Turn every batteries from every appliance in the house the wrong way around. Do not remove! If they've been removed then it becomes obvious whats happened. You want him to wonder if all his stuff is broken. That means the TV remote, mouse, keyboard, power tools, anything! It'll drive him mad for weeks.

The best revenge is for you to enjoy your life to the full, make the most of it:) Treat yourself to a new hairstyle a bit of pampering does wonders! Go out and do new things, forget the person who hurt you their not worth the energy. I wish you all the best.

Don't let those people have one more minute of your soul! Living well is the best revenge, and while you go about living well, working hard, and doing for others, you will gradually heal yourself from the hurt which was imposed on you. Take the high road; it leads to much nicer places.

Sometimes revenge is the only way to go... especially if they've really hurt you, and knowingly done it too. A good one I've heard is similar to one below, and involves raw fish.... Get some pilchards or really stinky fish and depending on wether he has them at home stuff them inside the hollow of a curtain pole. After a few weeks, the smell will really be unbearable and men being men won't ever think to look in the hollow of the pole! One guy that had this done to him (he's sent his wife packing and got his new bird to move into their home... didn't change the locks though) didn't know what it was, they got cleaners in but it still remained so they moved... and took the curtain poles with them!! Satisfaction guaranteed!
