Indeed, my short and dirty friend, I now recall using it in such a fashion, too. A very versatile little gesture was the chinny.
On things being scary – Bagpuss was actually quite an intimidating beast if you took into account the size of his bloody great gob; terrifying to a small child. Chris Moyles does a good impersonation of the Terror Cat just by existing and we all know that he ate some of the mice when the cameras were turned off. Bagpuss that is, not Moyles…
Edited for the awful spelling of the cat’s name.
