I was in the kitchen watching TV with my wife the other day when a news item came on showing the Swiss Re Building – you know, the one that’s colloquially known as The Gherkin.

‘Oh look, there’s The Porcupine,’ she said.

‘The Porcupine?’ I replied.

‘Yes, that building – it’s called The Porcupine’.

‘It’s actually known as The Gherkin,’ I informed her. ‘Because of its shape’.

‘Oh, I must be getting it mixed up with that building in Glasgow,’ she replied.

‘Which one is that darling?’ I asked

‘The Armadillo.’
