I remember talking about metaphors as a child at school. The kids were giving examples such as 'as blind as a bat'. I piped up with 'cold as a penguin's chuff'. It wasn't until years later I realised that a) the teacher really did look that horrified; and b) a penguin's chuff is NOT the feathers on it's tummy, regardless of what Dad had said.
