Plot summary
Elaine must take baby steps with her jazz club saxophonist boyfriend because he balks at oral sex, but Jerry takes matters out of her hands by overselling the couple as "hot and heavy". George's parents meet his future in-laws for dinner; ignorant of refined dining customs, they bring a loaf of marble rye which gets neglected, and steal it back out of spite. Not needing bad blood between the families, George needs to replace the loaf behind the Rosses' back, so he enlists Kramer to take the Rosses out on a romantic hansom cab ride. Jerry resorts to robbing an old woman for her marble rye.
