I seem to remember, a few years back now, a brief craze for rocks as pets.
You could get accessories for them - I remember a leash for taling it on walks, a training whistle, "kennels", and a warm waistcoat for cold days.
The height of the craze came when it was announced you could buy an "attack" rock, to safeguard your home and loved ones !
Hmmmmmm............... and you think a blank book is strange ?
