This 6.6-second clip features Rick Astley singing the opening line of 'Never Gonna Give You Up,' 'You know the rules and so do I,' in his smooth, familiar pop vocal. It lands as playful and instantly recognisable, turning a sincere love-song lyric into a knowing wink. The line comes from Astley's 1987 hit, later adopted as the classic Rickroll prank.
