After an unfortunate encounter with an Exacto knife, Jerry (Jerry Seinfeld) receives an infusion of Kramer's blood -- and he isn't keen on being regarded as a "blood brother." George (Jason Alexander) finds both his appetite and his libido increasing thanks to some vanilla-scented incense. Elaine (Julia Louis-Dreyfus) works overtime to prove she is responsible enough to watch her friend's child -- then wishes she hadn't. Phrases key to the action include "pinch weasel" and "free love buffet"; and as a bonus, Lloyd Bridges returns as octogenarian health freak Izzy Mandelbaum.
