Ha ha..what a stirer you are Sam!
I have absolute reservations about this idea, but Everyone deserves the right to their opinion and belief. I bought a pair of bengalese from a friend for the first time in May and he used his wedding ring in this same manner. I held my tounge and happily walked away with some nice birds.
Also during my Wife's baby shower with the same method my child was decided to be a Girl, However the magic force must have been misinterpreted on this day because I now have a lovely Son Blake. All good fun.
On a similar note to Sam's, in the past I have seen some good examples of Chick Magnets working that displayed quite good results. Quite a valuable thing if you are fortunate in this way.
Cheers.
