I've had a think about this. I went to Durham, and the term Merchant banker did indeed apply to most of the undergrads (ironically, many became actual Merchant Bankers). However: 1. According to "The Diary of a Teenage Health Freak" average male produces 5ml of ejactulate IIRC. 2. These are fit young men, and the university had some really fit young women when I was there. So let us assume something more like 10ml for safety. 3. There were never more than 9 people sharing one shower. Assuming that each male took a shower every day and they relax in a gentleman's way, that is only 90ml of ejaculate per day. I doubt that would block the drain as, presumably, each time there was already a much greater amount of water flowing. Additionally there will be relatively little hair as these people will all be under 21 and therefore mostly not going bald. It might of course block the drain if the 9 gentlemen involved took turns firing directly into the plughole without the water running, but I doubt they'd have the organisational capability. Even so, this isn't beyond the realms of possibility, if some of the rumours I heard whilst I was there were true. I suspect this is probably an intercollegiate prank (the colour of the door fits my old college, University, so I'm prepared to guess the pranksters were Hatfield College) . In typical Durham undergrad fashion they have also aped one of the proper, old universities. The real givaway is the fact that the Estates and Buildings department managed to spell Masturbation properly, they certainly wouldn't have managed this in the old days, though spell-checkers have improved greatly since 1880. Hope this helps.
