Seinfeld: The Blood

Jerry's parents hire an old friend to train Jerry as they are worried that he has started to gain weight. Jerry also has an accident with a knife and ends up requiring an infusion of blood, which happens to belong to Kramer. Jerry is not excited about becoming 'blood brothers'. Meanwhile, George thinks that his 'performance in the bedroom' is improving because of vanilla scented incense so he starts incorporating food and television to further improve his performance. Elaine visits a friend who implies that Elaine isn't responsible enough to watch over her child, so Elaine works over time to prove otherwise.
