I was once 'fraped' by a former (non technical) manager. I decided to retaliate by returning the favour while he was out of the office, but instead of the basic toilet humour I had been subjected to, I took it one step further and posted a status on his behalf, a sensitive cry for help, full of sadness, regret, alluding to betrayal and broken friendships. The texts, calls, concerned replies and messages on Facebook started flashing up his phone. He called me demanding I delete the status now as he couldn't figure out how to do so from his phone. Needless to say he was not happy. Highly recommended.
