[1] In this episode, Elaine mistakenly mails out a Christmas card in which her nipple is exposed to all her friends and relatives, Jerry's girlfriend breaks up with him after she sees him seemingly pick his nose, and Kramer is angered when he learns Calvin Klein has put out a new perfume based on his idea for a perfume that smells like the beach.
The exposure is subtle enough that no one notices it until after Elaine has mailed out the Christmas card to all of her friends and relatives, including her underage nephew and her morally conservative boyfriend.
Jerry has a date with Tia Van Camp, the Calvin Klein model he met on the plane in the previous episode.
After the date, Kramer identifies the perfume Tia is wearing as the one he pitched to a Calvin Klein representative in "The Pez Dispenser", called "The Beach".
Jerry launches into a rant about how people who pick their noses should not be socially ostracized, with references to The Merchant of Venice and The Elephant Man.
