Stephen Colbert & Steven Pinker

Prof Steven Pinker was asked about his hair and more importantly - how does brain work? His answer had to have five words or less. Pinker's brain cells started to fire in patterns and he said:

• brain cells fire in patterns

Very cool. The discussion continued by the topic of denial of human nature, what can brains of infants do, grammar of profanity. Colbert himself showed that he has brain damage that prevents him from swearing. When he tries, it beeps.
