How did you guess.....
Mind you saying that, even when I wasn't single the missus used to help me with the sabotage
Like when one of my mates was getting it on with one of her mates in the living room...How unfortunate for them that me and the other half decided at that moment that we wanted to watch south park in the living room.
So we just walked in, turned the TV on and sat down. Didn't say a word. And they didn't say anything either. They couldn't, they were guests in our house hehehehehe. Oh such a vulgar display of power.

(we were drunk...thats my "i'm not always an asshole, honest" disclaimer anyway. Besides, they were both a pair of twats anyway)
