Sir, I thought your readers might find this interesting. Whilst visiting a local garden centre, I came across some rather unusual garden decorations (Figs 1-2). I was wondering quite who might want such things in their garden; perhaps these are modern day scarecrows influenced by an experience of dentistry?

Both stones seem to be 'hatching' a smile and perhaps the rudest has been influenced by a Rolling Stones album cover? (Although these stones were still!)

It is good to see that such unzipped stones are demonstrating a good oral hygiene example.
