Oh Sketty trust me he smiles all the time he just doesn't like the world to know it.
There's been many at time when I've tried to take a picture of him & he stops me because he can't get his grumpy face right without laughing.
He's a con man Sket & he's fooling you.
I would even go as far to say he's the happiest person I know.
You may all be assured that I am monitoring these libellous attacks on my good (miserable) character.
Meanwhile, you may be interested to know that the '3D Rude Bison', from IJB Products, will soon be available from branches of Wilkinsons, Woolworths etc, priced at only £19.99.
