i had this really asshole boss he was not at the top but he was my superior at work , he was always ordering me to clean up after him and yelling at me if i didn't clean up after myself , it annoyed me for months. one day i noticed he was a bit to friendly with one of our co-workers she was 22 and he was 53 (!!) i figured this could be useful, next time i was at work i waited untill he left his office i knew he had his facebook page open so i went on it and found the conversation between them , it turned out they where in a relationship and from what i could gather on the 10 min i had it was really secret , i went back to my work space and found his gf on facebook under family her parents names where listed, now i had everything i needed to run my gag.
when the end of the day came my asshole boss came in as always and told me to clean up his office, i looked him straight in the eye and told him " unless you want her dad and mom to know some 53 year old pervert is having sex with they're daughter i suggest you go clean it yourself , and from now on you do as i say got it?" i gave him a quick tap on the cheek to get him real mad and then turned and started walking .. he came running after me yelling "you little shit!" i ran about 10meters before another co-worker tackled him, he got fired at the spot.
