I did one of the 'personality tests' on Facebook.
Seeing the supposed description of me, I got some 'you're having a laugh' e-mails from a colleague. I protested that it was in fact completely accurate.
She of course was having none of it, and it went back and forth in this vein for some time until she ended the banter with the killer line "I laughed so much at that I thought I'd have to borrow a Tena Lady from Doris (*)"
Not much you can say to that really.
