At my last job I was on the same level as a colleague, ie we did the same job. We got on fine but could rarely have a laugh as he had the personality of a brick wall. A year or so after joining a supervisor position came up, so I stuck my name in the hat and so did he. I went on holiday for three weeks and came back to him being my supervisor. No problem, missed that opportunity. Turns out he was actually banging one of the girls in HR at the time. Once this particular cat was out the bag, the manager walks in to his office with one of the supervisor's emails in his hands and says "please can you ask your girlfriend in HR to proof read your emails if they are going external" and walks out.
Supervisor runs after him and asks why, to which the manager replied, very loudly, BECAUSE YOUR WRITING LOOKS LIKE SOMEONE DRANK A BOTTLE OF RUM AND A CAN OF ALPHAGHETTI SPAGHETTI AND PUKED THE SPAGHETTI ALL OVER THE SCREEN.
He was a great manager that man.
