Mine would certainly be much bigger than the one that this chap here has been blessed with I can tell you. I'd like to design it myself and make a much better job this time than the one I tried to fashion out of blue plasticine when I was about six. Perhaps it's best that I spare you the details aside to say that it had major constructional flaws and didn't cut the mustard at all.
To my utter surprise there are others of the fairer sex who are horrified when I present this scenario to them. They have no desire to swap their girlie bits for a dangly appendage of their own creation even on such a temporary basis. I found this out when I brought up the idea in conversation with some social services colleagues. It must have been a rare quiet day. 'What would you do with it?' asked one in a bemused fashion. Of course I've had years to think this through. 'Lots of things.' I replied 'I'd wee out of train windows, see how far I could stand away from the toilet whilst peeing and uh....I'd stick it in things.' Her response to this last idea was priceless. 'So the pie section at Morrisons wouldn't be safe from you then?'
