This week on Mad Men:

Pete brings in another big client, Honda.  Roger doesn't like the idea because of World War II.  Pete calls him out on the fact that Roger just doesn't like when other people bring in new accounts.

In a contest with two other agencies, Don figures out a way to both win the Honda contest and bankrupt Sterling Cooper Draper Pryce's biggest competition.

While staying with Don, Sally cuts her own hair and gets in big trouble with Betty for doing so.  She then acts out again and Betty can't handle it anymore.  After talking with Henry, she decides to send Sally to a psychiatrist four days a week.
