Which episode features the famous 'Zou Bisou Bisou' scene?

The famous “Zou Bisou Bisou” scene appears in “A Little Kiss,” Mad Men’s two-part fifth-season premiere.

During Don Draper’s surprise 40th-birthday party, his new wife Megan performs the French pop song for him in front of their friends and colleagues. Jessica Paré, who plays Megan, sings and dances with deliberately provocative confidence while Don reacts with visible embarrassment. The moment became one of the series’ most recognizable scenes because it exposes the couple’s private intimacy to the entire office.

The song itself originated in the early-1960s yé-yé pop tradition. Gillian Hills recorded a notable French version in 1960, while the English-language version was known as “Zoo Be Zoo Be Zoo.” Mad Men’s use of the song also highlights the cultural and generational contrast between young, French-Canadian Megan and the older advertising executives around her. Viewers sometimes confuse the scene with “The Phantom” or “Signal 30,” but it occurs in the season-five premiere, “A Little Kiss.”
