Lanette is a woman whom Jerry dates in "The Summer of George". He planned to take her to the Tonys and when he arrived at her apartment he found another guy there, a "dude", and their relationship is unclear, much to Jerry's dismay. Eventually Lanette decides to drop the "dude" and dates Jerry exclusively. Jerry, however, soon becomes worn out by her busy lifestyle. As a result of this, George decides to become Jerry's "dating assistant"; one of George's first tasks is to buy invitations for Lanette but he is unable to deliver to invitations (he was busy playing "frolf" and later he slipped on an invitation, leading to him being sent to the hospital). Presumably, George's mistake led to Lanette and Jerry's breakup. Lanette was portrayed by Amanda Peet.
