Thanks Bob.... we dont have that expression over here :0)

There is an old family lives down the road called Munroe, all the male members were nicknamed "Stoner"
Stoner Duncan, Stoner Neil, Stoner Alan
As far as I know its been a tradition for over 200 years but nobody knows where the name came from.

AS these old guys never smoked anything stronger than "Thick Black" tobacco, I guess it must have been sumphin' else.
I thought I had just unravelled a 200 yr old mystery :0)
