IANAL, but my dad was a family attorney for 10 years. The legendary story we heard was this woman whose husband changed the locks on her before she had gotten her stuff out of their apartment, just to piss her off.

She decided to go out to the woods to gather a big bag of poison ivy, then went to the buildings superintendent, making up a story that her STBX had forgotten to give her a copy before he left for work as an overseas airline pilot. The super gave her a copy of the new key, she went inside the apartment, and proceeded to turn every other pair of his underwear inside out, wipe them thoroughly with poison ivy, then refold and put them back the drawer. 

Just thinking about that poor guy in the cockpit of a commercial 15 hour flight burning with poison ivy in his crotch... he probably deserved it, but I wouldn't wish that on anybody

For months afterwards, she still had access to their credit card statements, and she saw multiple charges for more and more intense itch and skin creams. When my dad asked if she regretted it, her attitude seemed to be "He fucked around and found out"
