As a kid I had Bunnykins plates, cups, bowls etc - beautiful images of bunnies in waistcoats in English countrysides on porcelain-type crockery. Every second family had them. On the bottom of each piece was a little portrait of two or three of the bunnies.

It was only in my twenties that someone pointed out to me that those bunnies on the reverse side were doing, well, what bunnies do - sometimes in pairs, sometimes in threesomes, always very discreetly (but unmistakeably) in their little blue waistcoats. My parents had never noticed and thought it was hilarious when I pointed it out to them. I've since pointed this out to many others who grew up with these pieces - or better still, whose children did - and none of them noticed either.

Unfortunately I can't find any images. But if you or your parents have any bunnykins crockery, take a look.
