Episodes in the second series sometimes had "flash frames" (three frames, lasting 1/8 of a second), but these were cut out of some repeats. They were included to make fun of the British and American public's fear of subliminal messages in television and music. The images included the words "Carry On Cowboy" (the name of a 1965 film), a rusty dripping tap, a leaping frog, a dove in flight, a skier, and a hand making pottery.
