Hi, does someone knows where this gif is from?

It's from a 1974 film called "Sweet Movie". See my post here: https://umd.net/forums/our-favorite-wam-movie-scenes#postid_547166 The YouTube link in that post is no longer good but search for "Sweet Movie 1974" and you'll eventually find it with the egg scene around the 52:43 mark. Also note the chocolate scene at the 1:30:20 mark.

Thanks a lot!
