The Lucy-Desi Comedy Hour Season 3 Episode 3

Ethel's piano playing abilities seemed to vary greatly throughout the entire run of the Lucy series. In the first season of I Love Lucy, Ethel plays the piano rather well in "Breaking the Lease" and in "The Ballet." In the sixth season, however, Ethel confesses that her skills as a pianist are not very good in "Ragtime Band." In this episode, she plays like an accomplished jazz musician, but it's obvious that someone else is actually playing the music.
