This is a sketch from an episode of Dim Dam Dom broadcast on Dec 23, 1966. I'm not exactly sure what's going on besides it being a modernised version of the Nativity story, with Serge Gainsbourg as Joseph and Chantal Goya as Marie (Mary). Though I'm pretty sure that even if my French were better, I'd still be left scratching my head at scenes featuring nuns sashaying to Gainsbourg or Jacques Dutronc briefly performing in a meat locker. Plenty of fun, weirdness and great tunes, with an all star cast including Sylvie Vartan (intro) and Régine (full cast list at IMDB).
