First off, Hollywood types may have such limited cognitive function that trying to learn English from them is about as useful as listening to baboons. Their primary skill is in memorizing words that someone else wrote.
Second, this video is trying to pander to those who are socially and verbally insecure by discussing a performer whose routine is to act as though she has three functional neurons. (I suspect the performer is socially brilliant and very clever, but her act is to appear socially inept in ridiculous ways.)
Third, spoken English frequently requires high levels of interpretation. People speak as they think, and, without an opportunity to parse their words carefully, their utterances frequently do not make literal sense.
The topic of this video is how to carry on an extended phatic conversation. The point is that each party must give a basis for the other party to make a response, to provide the other party an opportunity to make an obvious and socially innocuous rejoinder, to "turn the conversation around."
