So much of advertising these days is empty visuals, pointless digital flash and dash, "sound and fury, signifying nothing," as Shakespeare wrote.
Back in 1970, copywriter Mike Coughlan, from the London ad agency Cramer Saatchi, wrote this ad (art directed by John Hegarty). He just took sterile copy from a government hygiene leaflet, made it conversational, and added the last line.
Keep writing, copywriters. You will always be needed.
