This is the episode in which BJ needs money to put a downpayment on property in Stinson Beach, CA. Charles loans him the money and then treats BJ like a servant. He later does the same to Hawkeye after paying off Hawk's bar tab and a round of beers. BJ and Hawkeye, seeking revenge, round up the gang to fleece Winchester in a game of poker.

The slip-up comes early in the episode when BJ is decribing the property in Stinson Beach. He says that it has a "beautiful view of the Golden Gate Bridge." Stinson Beach is nowhere near the Golden Gate Bridge and the are mountains between the two. There is no way that you could see the Bridge from Stinson Beach.

A little research with an atlas would have prevented this slip-up.
