Good ways to get revenge on a cheating partner (Extreme revenge - No limits)?

[¢σяя вℓιмєу]

I've found a few good ideas online so far but I'm after some more. I want them to be as creative and as extreme as possible.

Here are a few I've found online:
1. Urinate into her steam Iron so her clothes smell of p***
2. Send a pair of her knickers with a love letter to male relative of hers
3. Change all the names and numbers on her mobile so dirty texts etc go to her fathers phone
4. Use her car for a joyride in her works carpark and make lots of damage for the CCTV
5. Set up a new social media profile with facebook, twitter, etc and give her a new personality
6. Use her toothbrush to clean the toilet
7. Buy a homeless mans boxer-shorts and socks and put them in with her underwear (or in her handbag) (Or make her a drink and filter it through the crutch area.) NASTY!!! Haha

These are the best ones I could find. It doesn't matter how disgusting it be, in fact, the worst the better.
