Advertisements Ken was complaining that he couldn't meet with the client's new Head of Marketing because that was a position beneath him and it would make Ken look less important if he took a meeting with someone junior to him. So Joan figured she could act as Ken's "underling" and take the meeting on his behalf rather than cancel it. But then it turned out the meeting was with a young, hotshot MBA who was planning to fire SC&P and bring all the advertising in house. So Joan realized she didn't really have the depth of business knowledge she needed to counter this guy's arguments, so she went to the college to get a crash MBA course from the professor. Armed with her new info, she called the client's Head of Marketing and helped him understand that he'd be foolish to bring the advertising in house because he'd then have to compete for ad buying time with all the ad agencies, and also he'd be the one responsible if things declined, and the industry was already trending downward. This got that character to realize he was in over his head and he asked her what he should do. The only part I was confused about was why Ken was mad at her at the end. She did him a huge favor and if he'd stop being an ass for two seconds and ask her what happened, he'd find that out.
