Honorable mention goes to Saturday Night Live (no direct links to videos available, sorry.) SNL did a set of four parodies: One directly based on the Chanel ad and then others on Taco Bell, dog condoms and famous New York dermatologist Dr. Zizmor.
Just as Pavlov's dog learned to associate the sound of a bell ringing with dinnertime, rats can learn to associate flashes of light with how long they must wait to receive a sip of water.
