Just had a look on the Saint's website (the official one) and in a box on the right hand side of the home page there is a 'On This Day' tab. Clicking on it, you see a list of events. Birthdays, Last matches and ironically, one labelled 'Signed On'. What struck me though is that the list for this section only contains two names.

Oh come on now. Ive managed to hold a job down for 15 years now.

Although I am the only one in our street.

And you work in the benefits office...
