This is a roughly six-second sung snippet built around the line 'you know the rules and so do I,' delivered in Rick Astley's smooth pop style before the goodbye turn. It feels playful and knowing, because most listeners spot the setup at once and wait for the familiar payoff. The line comes from Astley's 1987 song 'Never Gonna Give You Up,' the track behind the long-running Rickroll joke.
