The film received some harsh reviews in France, which affected Étaix's next film, As Long as You've Got Your Health. Jean-Luc Godard included Yo Yo on his top-ten list of the best films of 1965. The American comedian Jerry Lewis saw the film during a visit to France and enjoyed it so much that he asked to meet its creator. A French television team that had been appointed to interview Lewis captured the meeting, where the two comedians, limited by the language barrier, made impressions of each other's comedy routines and improvised clown acts together. Lewis later cast Étaix in his own unreleased film The Day the Clown Cried.
