*I* don't even remember the story behind that one anymore.
GGG (formerly jmskitten), my ex-gf from a few years ago, went with my girlfriend at the time and my boss's wife at the time to get some syrup and toilet paper and covered my car in it while I was sleeping in my apartment. My gf feeling guilty calls me and starts talking to me and asks if I would be mad if she and GGG/boss' wife covered my car in toilet paper and syrup. I said yes, I was be very mad. She told me not to look outside then (it was 2am). Sure enough, there was my car, covered in syrup and toilet paper.
I told my girlfriend that I was gonna hang up on her. I did and then proceeded to call GGG and the boss' wife. I chewed out the boss' wife (we are all friends) and made her feel like utter shit. Not my finest moment but I was really stressed that week. I made GGG cry several times because she liked me at the time (I had broken up with her by that point) by telling her that she was stupid for doing that. Eventually, though, I forgave them.
I used to be so bitter about everything a few years ago. Now I save that for the internet >
