Both families obsess over a loaf of rye bread that wasnt served with the meal, which Frank takes back home. Elaines boyfriend writes a song about "their relationship," which later has a big impact on his career. Kramer takes over a friends horse-drawn carriage for a week and helps George out with his scheme to replace the rye bread.
