Plot summary
Everyone goes to a Hamptons beach house to see their friends' new baby. George expects to have sex with his girlfriend Jane for the first time, but everyone else sees Jane topless before he gets to. Rachel sees George's shrunken penis after a swim, and gossips to Jane, while George realizes in horror that women do not know about "shrinkage". Kramer treats everyone to stolen lobster from a fisherman's trap, outraging their host, and tempting Rachel to violate her kosher diet. The guests are revolted by the ugly baby, but the family pediatrician delivers the same compliment to Elaine and the baby alike.
