Lectures: words not in the dictionary

I recently found a lecture by an eminent lexicographer on the project of listing all of the words of English — far more, he claims, than are found in any dictionary. The content is very interesting but the language used is really very poor in comparison with that others whose speech exemplifies spoken English as an art form (Stephen Wolfram’s lecture, for example, which I shared earlier).  Indeed, the speaker, Chris Cole of Harvard and Caltech, commits grammatical crimes in about every third sentence, a ratio which, though deplorable, is probably quite common among American English speakers, as spoken language is not generally expected to conform to the norms of formal English in this country. Here is the talk: http://www.youtube.com/watch?v=kU_CiErwkFA
How many grammatical errors can you find?
