They stop at a gas station in Tulsa, Oklahoma. The station attendant comes out to chat with the husband as he's refueling and asks, "Where y'all heading?"

The husband replies, "We're going to California." The wife rolls down the window and asks her husband, "What did he say?"

The husband turns to his wife and says, "He asked where we're going!"

The attendant then asked where they came from. The husband replies, "We're from Cape Cod."

The wife rolls down the window again and asks, "What'd he say?"

The husband turns to his wife and says "He asked where we're coming from!"

The attendant says, "I was in the navy years back...I got to drop anchor up in Boston."

The husband replies, "Oh wow! We're originally from Boston." The wife asks the husband again, "What'd he say?" The husband again tells his wife, "He said that he spent some time in the navy in Boston!" The wife smiles and nods. The attendant then says, "Yeah I remember that last shore leave in Boston, me and the guys looking for some action, end up in a dive bar and I met this girl. We got a room, and she was the the worst fuck I've ever had!" Again, the wife asks, "What'd he say?" The husband replies, "He thinks he knew you!"
