Funny words

My daughter, when she was about 9, was asked to name parts of the body for homework once, the more obscure the better. So to encourage her to think about it too, my mum and I asked her to say certain words.
We suggested the medical word for skin, which is dermis. To get her to think we said, 'What do you call a thick person?' to which she replied, 'A der?'. We then asked, 'What do you call a lady that's not married?'
She said, 'A virgin?'
Ah, the innocence of youth!
