Synesthesia

The Porcupine was happy to see the Octopus. 'Hi. What's up? ', he greeted his friend. 'Hi', said the Octopus. 'I am intrigued by synesthesia'. 'Oh, really? What's that? ' asked the Porcupine. 'Oh, you know, a condition in which a sensory experience associated with a modality occurs when another modality is stimulated.' 'I don't understand this', said the Porcupine. 'Oh, you know, said the Octopus, for example, you taste a food and see a color, or you hear a sound but you feel hot or cold.' 'Very interesting', said the Porcupine. 'It's like what happened to me the other day when I met this chicken accompanied by a goat. The chicken was bleeting and the goat cackled.'
