First, he meets Karola Faber, the German wife of a U.S. G.I. who has found life in the States not all it's cracked up to be: she has left her husband and makes her living through prostitution. Peter and Karola visit the local German emigré community's Oktoberfest, and win the festival's King and Queen crown. Their prize is a cow, which accompanies them on their further journeys in New York City.
