His father misunderstands him, and believes that the prince wishes to 'sow his wild oats' before settling down with his arranged bride. The prince sets off to New York, and picks the area of Queens as the best place to look for potential brides.
Needless to say the potential for comedy is high.
Look for the part of the film where three old men are gossiping in the barber's. All of them are played by Eddie Murphy.
