Put A **** On It

As Melbourne peeps maybe already aware, the Finders Keepers market is on this weekend.
It will be the the perfect antithesis to the Grand Prix also on this weekend. No petrol fumes and Rev head free. I lived in fairly close proximity to Albert Park lake the first year it was held in Melbourne and was continually irritated by the persistent nnnnnooowww of the stupid race cars doing their laps.
I'm sure you'd want to be as far away from that as possible. You do? Good.
And for added incentive I am offering a 10% discount to all Betty Jo customers if they can tell me where this phrase comes from.....
