Oh dear, I just thought of a job-related cok-up..lol
I started my new job six months ago, and my new team leader was to be a guy I used to work with in a previous job, but he was off sick the day I started. So I went into the office, and my new colleagues mentionned the team leader, so I went "yeah, he was a bit wild at the time, I remember him having a really awful argument with his girlfriend at the time in the pub, he was sooo drunk!".
Turns out one of my colleagues is his new girlfriend. Ooopss!
