I used to have a 'lucky' pair of underpants that I would only wear for matches, and my succsess rate was quite good during that time.
How these got to be my 'lucky' underpants I will not elaborate upon, suffice to say it had something to do with a rather lovely Scandinavian actress in Stravanger in the mid 80's.
Multiple washings and a little enlargement around the midriff in recent yearsdeemed them no longer usable, sadly.
These daysI rely on my 'lucky' FM cap.
(not that it did me much use last weekend!)
