Jerry dumps his girlfriend, Sidra (played by Teri Hatcher), after Elaine convinces him that her breasts are probably the result of implants. Kramer claims a man at the health club who introduces himself as "Sal Bass" (played by Tony Amendola) is actually Salman Rushdie. Later, Elaine and Sidra are in a sauna together, and Elaine accidentally grabs onto Sidra's breasts to break her fall after tripping. Elaine later goes to Jerry and admits that she now thinks that Sidra's breasts are real and "are spectacular". Jerry decides to take Sidra back. However, Elaine later carelessly enters Jerry's apartment when Sidra is there, cluing Sidra in to the fact that the two of them are friends. Thinking he had Elaine deliberately feel her breasts in the sauna, Sidra dumps Jerry; as she leaves, she tells him: "And, by the way, they're real... and they are spectacular!"
George accompanies his current girlfriend, Betsy (Megan Mullally), to Detroit for her aunt's wake, hoping to accelerate their relationship by being supportive in the midst of her grief. While there, he tries to get a copy of her death certificate so he can get a 50% discount on the airfare. However, he gets into an argument at the funeral reception with Betsy's brother, Timmy (Kieran Mulroney), over the social acceptableness of double-dipping a chip. It devolves into a disruptive fist fight, leading an upset Betsy to break up with him. Lacking the death certificate, he shows an airline clerk a picture of him next to the casket, but the clerk does not consider this sufficient proof.
Sidra's parting shot to Jerry at the end of this episode was scripted as simply "And, by the way, they're real." Teri Hatcher ad-libbed the kicker "...and they are spectacular." This line is repeated by Jackie Chiles in "The Finale".
The television show MythBusters tested the theory that double dipping was like "putting your whole mouth right in the dip" on the April 22, 2009 episode. The MythBusters found that double dipping produced fewer microbes than putting all the dip in your mouth. Also, the amount of microbes present was negligible compared to the amount found in regular dip.
In Salman Rushdie's non-fiction book Joseph Anton: A Memoir, Rushdie recounts bumping into Jerry Seinfeld at a cocktail party where Seinfeld nervously asked his opinion of "The Implant" and "visibly relaxed" upon Rushdie's telling him "that he had thought the episode very funny."
